Our company has been professionally providing each of these services for more than 10 years. We have the necessary expertise and experience. JazzTeam employs proactive professionals who can become a part of your team.
Our company offers comprehensive project handling, as well as effective solutions for individual tasks. We often cooperate with customers in several service areas at a time: we combine backend development and manual testing or frontend development, test automation and project management.
JazzTeam provides a comprehensive service for the design, customization, development, and integration of IT products. We are focused on creating high-tech solutions for the achievement of our customers’ business goals and are interested in active participation in projects. With our extensive international experience and highly competent staff, we offer the following services.
Types of JazzTeam software development services
We create scalable, stable products that customers can easily maintain on their own and without additional effort. Our team initially provides a high level of code coverage with easily extensible automated tests, creates required documentation and manuals on the use of systems. The IT solutions we develop have a modular architecture and loose coupling of components, which allows to ensure the effective implementation of new product features.
JazzTeam has experience in creating its own products for commercial and internal needs: from idea generation to selling an out-of-the-box solution. One of our products is XML2Selenium. It is a Java-based extensible platform for creating and monitoring automated tests. We also use our own product for employee time tracking and create solutions for crawling. We have gained the necessary practical experience and skills of building a product development process from scratch.
We will be glad to help you with setting up IT solutions creating processes, as well as ensuring the delivery of a stable working product to the market in the required time.
We develop and optimize various IT solutions for specific customer needs. It results in process improvement and higher business efficiency. Since its creation, our company has been specializing in Java backend development. However, in order to be a reliable partner for our customers and approach project tasks in their entirety, we provide both backend and frontend development services.
Front End and Back End Development
For more than 10 years JazzTeam has been focused on Java technology. One of our greatest strengths is server Java development. We create different types of Java solutions for a wide variety of application servers and execution environments. While developing different software types we rely on OOP, design patterns, recognized architectural paradigms and approaches, which allows us to ensure a high level of reuse of created modules. In addition, our engineers have expertise in creating projects in the plugin paradigm. Also, we apply best practices and approaches to development and testing: Model Driven Development, Test Driven Development, Data Driven Testing. Adhering to engineering standards and approaches, we have extensive experience in building the architecture of various software types.
Due to the engineering approach, we professionally refactor a complex, hard-to-maintain code and ensure a high level of reusable components. All this allows reducing the cost of product support and involvement of new specialists in a project.
Our competences in Java development
Comprehensive and systematic knowledge of Java technology:
Wide range of working tools and frameworks:
We are not limited to only server-side technology and actively apply other programming languages. Constantly using Java to create backends and integration solutions, we have experience in building backends in Node.js, frequently use Groovy (both for scripting and for creating complete backends), as well as Kotlin. We are proficient in technologies historically associated with the Java ecosystem (XML, XSLT, XSD).
We are experienced in creating backends for the following software types:
Our team is competent in developing IT solutions for various business domains. Including:
JazzTeam professionally uses JavaScript and related web technologies: HTML5/JS/CSS, AngularJS, ReactJS, Redux. Our frontend developers learn OOP and design patterns. When building the client-side logic in JavaScript, they use architecture and pattern-based thinking from the world of Java. Applying JS frameworks (AngularJS, ReactJS, etc.), they deeply understand how they function. They study the source code of popular Open Source solutions and repeat best practices when writing their own frameworks, which they create in an extensible OOP style following Java standards.
Our strengths in frontend development:
With our extensive experience, we often act as consultants for improving the application frontend part for the customer’s team. Our specialists can solve problems related to the compatibility of application components with different browsers, and advise on the efficient refactoring of legacy code.
This service includes applications reengineering using best development practices. During system modernization, we evaluate the state of a product in terms of the architecture, technologies used and processes executed, and propose options for further code development. Before we start manipulating the codebase, we try to create the necessary Unit and Data Driven tests to monitor the stability of the system during subsequent changes. All problems found are covered by Unit tests preventing the reoccurrence of eliminated defects. By doing so, we ensure regression testing of our patches in all versions of your product, which makes the refactoring process more stable. Due to the engineering approach, we professionally refactor a complex, hard-to-maintain code and ensure a high level of reuse of developed components. All this allows reducing the cost of product support and involvement of new specialists in a project.
Our company also provides cloud architecture development services, integration with Amazon cloud services, Windows Azure and other PAAS providers, migration of your applications between cloud providers. If using a cloud does not fit into your privacy requirements, we organize scalability by clustering on local servers.
JazzTeam has solid experience in developing integration applications. When creating such solutions, we use the company’s collective expertise in building the architecture of complex IT products. Our specialists professionally design extensible, easily integrated (including plugin) architectures, use different integration paradigms, such as SOA, Microservices, various Message Brokers and ESB (RabbitMQ, ActiveMQ, Apache Camel and Apache Kafka). JazzTeam engineers have expertise in the application of the MuleESB integration platform. When necessary, our specialists pass the MuleSoft Certified Developer: Integration and API Associate certification. Also, over the years of working with MuleESB, we have gained extensive experience in creating commercial Mule connectors.
JazzTeam has expertise in integrating various applications with such platforms as Salesforce, Zoho CRM, and Magento.
Our company solves complex, non-trivial problems that require long-term research using a non-typical technology stack or a combination of technologies, which is particularly topical in the early stages of product creation. JazzTeam has developed a unique approach to solving complex research problems. Our engineers start their work with decomposition: a breakdown into subtasks lasting 1-2 hours. In the following weeks, they spend one hour every day on this research, which in the end leads to excellent results. Practice shows that without getting hung up on one problem, a solution can be found faster. Application of this practice allows to perform effective research even within a limited budget.
We have substantial experience in technological research, effectively work on projects where the customer doesn’t yet have an exact idea of the ways of implementing specific solutions to achieve a business goal. In this case, we perform the necessary research building a technological foundation. Then, in subsequent iterations, we can proceed to implementation or stop cooperation at this phase and provide the customer with a detailed expert analysis, estimation, architecture or prototype of the future product.
We solve complex R&D tasks. For example:
Working with JazzTeam, you get not only a high-quality product, but also a comprehensive solution for issues related to test and release management. During IT solutions development, we provide professional manual and automated testing services and implement continuous integration and delivery (CI/CD) in all projects.
Our company has been creating automated tests since 2011. Our portfolio includes projects with 5000 and 8000 autotests, as well as provision of test automation service to regular customers from Europe, USA and Russia for 5-6 years.
Over the years of work we have successfully completed more than 50 projects on test automation, gained extensive experience in this area and developed a comprehensive approach to autotesting. Our company focuses on the effective combination of engineering thinking in autotests creation, expert CI/CD mastery, and professional test management. This approach allows us to solve complex tasks comprehensively and share our own culture of using best practices in development and testing with the customer.
We apply CI/CD (Continuous Integration/Continuous Deployment) on all our projects. The autotests we create are integrated into CI/CD processes right from the start and become immediately useful, paying off your investment in autotesting. Our company ensures a high level of testing process organization through professional management and guarantees the application of best practices in autotests and product quality management. In our work we use all available tools and effective approaches related to test automation. For example, Test Driven Development, which is often used in Agile projects. Our test automation engineers are big fans of Data Driven Testing. Over the time of using this approach, they have accumulated serious expertise which allows them to efficiently and quickly cover and stabilize the most important parts of a product.
We create scalable autotests with a clear structure that are easy to develop and maintain, accompany them with high-quality documentation and organize the test management process, set up CI/CD so that our customers can independently manage the launching of autotests.
Focusing on Java technology for the creation of backends (server-side), we use our expertise in other areas as well. In autotesting, we constantly apply best design and development practices: use OOP, patterns, UML diagrams, provide a high level of code reuse and maintainability, apply refactoring and code review.
Our test automation services include:
We apply an extensive technology stack for test automation and can choose the right tools for you. When testing isolated methods, we often use Mock objects. We use Selenium/WebDriver, Selenide, Selenoid, Concordium, Karma, and Jasmine for testing web interfaces. We perform load testing with JMeter.
Our company has been providing manual testing services for over 10 years. We have accumulated strong expertise in this area and have gained experience in successful quality assurance and stabilization of various products. Among other things, we performed manual testing of the following software types:
An important feature of JazzTeam’s manual testing service is the engineering approach. Our QA specialists are proficient in the necessary tools and types of scripting and are constantly mastering new techniques. For example, they use Postman for making requests to REST API, and SQL for database testing. All this allows to effectively use the team resources and save on development.
Advantages of JazzTeam’s manual testing service:
Proactivity and a desire to add value to the customer are important components of our service. Working on projects, we always offer the customer new ideas and solutions that can improve the product processes and technology. Also, at different stages of the project life cycle, customers may face difficulties, questions, and additional risks. Regardless of the type of service we provide, we always discuss and solve arising issues. During our work, we transfer our experience and offer implementation of best practices and approaches that will benefit a product and help to save money.
In some situations, customers need a professional consulting service. This type of service is especially useful when it is required to apply a comprehensive approach with a detailed analysis of the situation and the development of a strategy for implementing improvements. For example, in case of a huge number of accumulated bugs, problems with delivery or organization of processes, which often make obstacles for the product’s development and increase of sales.
Our company solves various problems related to the technical side of a product:
We provide the following IT consulting services:
1. Establishing the processes of risks planning and assessment, software development, quality assurance and delivery.
2. Project management with the implementation of Scrum-methodology and professional use of Jira.
3. Developing a strategy of implementing continuous integration and delivery (CI/CD).
4. Product technological upgrading:
5. Consulting on organization of complex and innovative technological research (R&D).
6. Improving the psychological atmosphere in the team. Overcoming learned helplessness in specialists, eliminating the psychologically tough atmosphere in the team.
7. Consulting from the current funder on solving complex business problems and conflict mediation (zmicer.consulting).
Consultations can be combined with coaching and work of our specialists in your office. The effect of such cooperation is not only an improvement of the technical side of the product itself, but also of the customer’s business in general. Among other things, it allows to improve the team’s work organization and increase the company’s profitability.
In the most difficult situations or at the initiative of the client’s top management, our CEO Dzmitry Harachka (providing IT consulting services as an independent expert, zmicer.consulting) gets involved in solving complex issues on the project.
With a high level of empathy and solid practical experience in IT in various positions, as a technological leader of his own company and an entrepreneur, Dzmitry can quickly understand your pains and offer feasible strategies and solutions.
The successful delivery of services by our company is based on a well-established project management culture with standardized and formalized processes. Each JazzTeam manager is driven by this culture and can influence its development and enhancement. Due to competently structured processes and professional management, all projects in which our company participated, were completed successfully.
Strong management is an important part of our services. Active participation of a project manager initiated by our company does not contradict Agile approaches and full-fledged self-organization of а team. A project manager in JazzTeam is also a Scrum Master acting as a mentor and leader. His main task is to coordinate the interaction with the customer and monitor the team performance. This includes facilitating communications and setting up processes on our part.
Our managers build effective processes, implement the necessary task management and test management tools, and apply the best practices in product development. As practice shows, this approach contributes to the improvement and efficiency of processes on a project and reduces non-production costs of engineers resulting in cheaper product development for you.
Project management
When necessary and when requested by the customer, our managers timely begin escalation, as well as use the expertise of other managers or involve the company’s management in the project. JazzTeam regularly holds weekly managers meetings, at which specialists share insights and challenges gained on the project. Working with us, you get access to the management expertise accumulated over 10 years of company’s work.
JazzTeam managers, in addition to their management expertise, also have a technical background and the necessary knowledge. Among other things, they can establish the process of CI/CD implementation and arrange regular work with the technical debt in a team from scratch. They perfectly understand developers, communicate with them in the same language and convey the value and benefits of implemented practices – regular Unit Testing, continuous integration and delivery – to the team.
Ordering a project management service from JazzTeam, you get:
Any project needs competent management, so we can always start cooperation with providing this service. JazzTeam provides project management as a separate or associated service. For example, you can order only professional management for your project or get our project management services together with our team of test automation specialists or developers.
The concept of continuous integration and delivery is one of the key practices that our company has been strictly adhering to for more than 10 years. Introducing CI/CD, we improve the technological side of a product and contribute to the optimization and improvement of processes on projects. Over the years, we have become convinced of the effectiveness of this practice and strive to transfer this knowledge to our customers. Experience shows that the earlier you invest in CI/CD implementation, the more money, time and effort you can save. Furthermore, the first significant results of the transition to this practice will be achieved just in a few months.
Why should you consider implementing CI/CD right now?
Benefits of Implementing CI/CD
1. Timely implementation of CI/CD ensures predictability and stability of product functioning and reduces the cost of its further support. With continuous integration and delivery setup, developer-written modules are immediately built into the system and pass daily testing (Unit, integration, and regression testing), which makes it possible to arrange regular deliveries being absolutely confident of the high quality of product versions.
2. Thanks to CI/CD, bugs are systematically detected at an early stage of development, which significantly reduces serious risks for the customer. Among other things, continuous integration and delivery helps to avoid reputational and financial losses resulting from bugs after the product is delivered to production.
3. CI/CD allows for the rapid implementation of business functions that can be used by the customer while product development continues. It is achieved by frequent commits, instant autotesting, and regular deliveries provided by this practice. Customers can check the effectiveness of the implemented solution much faster, which helps to save the budget and create a product that will be really in demand among users.
4. CI/CD facilitates monitoring and improving the development team’s performance. CI/CD disciplines engineers, requires to follow certain rules (Code Style), use best development practices (Test Driven Development, Unit Testing), update the common code branch on a daily basis, and strictly adhere to the processes. The customer can easily make sure of the engineers’ performance and the correct allocation of labor costs: he or she can always see the results achieved by the team and individual specialists during a certain period of time. Also, automation of a large number of actions that were performed manually results in team’s performance improvement and reduction of probability of errors in the product due to human factor elimination.
5. CI/CD is the first step towards technical debt prevention. Over time, regular work on the technical debt becomes more and more necessary and a very time-consuming task requiring significant investments. Eliminating the technical debt during each iteration should be the standard practice for the entire team, otherwise, it will lead to a situation where it is impossible to develop the product and increase sales. The sooner CI/CD is implemented, the smaller will be the technical debt, and therefore the cost of its elimination.
6. Due to the implementation of CI/CD, every project participant feels involvement and responsibility for the successful release. Implementation of CI/CD means establishing a certain culture in the team, in which software development and operational activities are performed in a coordinated and inseparable way. With this approach, the responsibility and interest of a specialist doesn’t end at performing his or her scope of tasks (testing, coding, etc.). By participating in the CI/CD process, each team member understands the current stage of the developed functionality and strives to achieve a common goal — to ensure a prompt delivery of software to users.
We implement CI/CD iteratively and painlessly, effectively overcoming learned helplessness and possible resistance of teams. We implement the full Continuous Integration cycle with Jenkins/Hudson (and any other CI/CD tools) and automate project building with Maven. If necessary, we use Docker and other container technologies for deployment automation.
We have expertise in the following areas of work related to CI/CD implementation:
After completing a product, a customer may have new ideas for changing or improving the system according to current needs.
Due to our approach and principles, we effectively solve product maintenance and support tasks. Our company from the beginning thinks through and ensures the simplicity and ease of further development of the application. At an early stage of development, we integrate continuous integration and delivery into the project workflow. For continuous monitoring of the system stability, our team professionally implements processes that allow influencing the product quality promptly, implements regression testing, and provides the customer with the necessary test management tools. As part of this service, we fix bugs in the application, maintain the work of autotests and create the necessary test documentation. All of this allows us to effectively develop and modify the product. We also accompany the system with the necessary documentation describing its work, create installation and operation manuals for applications.
In case you wish to start cooperation with us within this service, we will be glad to work based on a T&M contract.
You will get additional benefits working with us
We believe that any task should be solved comprehensively. As practice shows, the successful development and scaling up of a product is only possible with competent planning, timely implementation of best development practices and maintaining a friendly atmosphere in the team. So, even if you need only one service, specific specialists or implementation of individual approaches, working with us you will get much more than you expected.
Regardless of the type of service selected, we consult our customers on improving the processes and technological component of their projects. Our team can suggest new ideas on the implementation of necessary practices for your product, create a long-term strategy for its development and legacy code refactoring.
Already in the early project stages, our managers arrange the processes in such a way as to ensure the highest efficiency of the team and the necessary speed of release of new product versions. In our work we rely on Agile philosophy and Scrum methodology, our engineers are guided by extreme programming principles. Thus, regardless of the type of service you get competent management of your project.
On all projects, we first implement continuous integration and delivery (CI/CD) or significantly improve the existing CI/CD processes. With a customized continuous integration and delivery process, developer-written modules are immediately integrated into the system and pass through daily testing.
When we find bottlenecks in the product, we apply autotests to that part of the code. Due to the timely implementation of CI/CD and autotesting, we can establish regular deliveries of the product being fully confident in its high quality. Working in short iterations, we deliver new functionality every 1-2 weeks.
Transferring experience to the customer, striving to improve processes and the product are the most important standards of JazzTeam. Our team is dedicated to ensuring that after implementing the developed features and completing the project, the customer will not only get a great product, but also full confidence in its stability, high-quality code, as well as the upgrading possibility and cost-effective support. We achieve this high result through an engineering approach, timely implementation of best development and testing practices, and competent management.
We are always glad to interact with you!
