Working on major customer business challenges, we take a comprehensive approach to issues related to development, testing, management, and CI/CD implementation. The time-tested model of services rendering combined with the excellent technological level of employees and professional management allows us to successfully complete the most complex projects.
78% of our clients are regular customers. Having worked with us once, they continue cooperating with JazzTeam for several years. Customers appreciate our sincerity and proactivity, engineering approach to development and high expertise in process building. We aspire to establish strong relationships, in which we develop one product or create several solutions for a customer with our stable and well-coordinated team. By choosing JazzTeam, you give your preference to a service provider with a proactive approach. During our cooperation, we analyze the product comprehensively and offer new ideas and solutions that bring additional value to our customers.
In project management, our company uses flexible methodologies based on Agile and eXtreme Programming. Guided by Scrum practices, we use short iterations and seek constant feedback from the customer. This approach allows our customers to receive and evaluate the first significant results of the work in just 2 weeks after the start of cooperation, and to make sure of the transparency of our processes.
JazzTeam has established a value-based engineering approach to creating IT solutions. We always start the development process with the product architecture design, make UML diagrams (deployment, classes, sequences, components, etc.) that are necessary for achieving a common vision of the concept and functionality of the product between the team and the customer. Our specialists use engineering approaches and practices in their work. On all projects we first of all implement Continuous Integration and Continuous Delivery (CI/CD) or significantly improve the existing Continuous Integration and Delivery processes. When we find bottlenecks in the product, we cover this part of the code with automated tests. If there is a need to test a large amount of input data, we use the Data Driven Testing approach.
Since the founding of JazzTeam, we have been focused on developing Java-based IT solutions. Our founder Dzmitry Harachka is a Java expert who has been working in this area for more than 17 years. During these years, he progressed from an engineer to a company owner. With a huge experience in Java, our founder instills best development practices to the company’s engineers on a value level. JazzTeam specialists professionally design extensible architectures using Java technology and various XP tools.
Focusing exactly on the chosen stack and our vast experience in Java server-side applications development allows us to apply the best practices of this programming language to various aspects of our projects.
Adhering to engineering standards and approaches, we have extensive experience in architecture building and software design and constantly apply the best practices from the world of Java in other technological areas.
Timely implementation of CI/CD ensures predictability and stability of product functioning and reduces the cost of its further support. With configured Continuous Integration and Continuous Delivery process, developer-written modules are immediately built into the system and are tested on daily basis (Unit, integration, and regression testing), which makes it possible to arrange regular deliveries with complete confidence in the high quality of product versions.
Implementation of CI/CD includes continuous application of best development practices by engineers: it establishes a single coding style in the team, as well as systematic creation of Unit tests.
Thus, by introducing CI/CD and the mentioned practices into a project, we improve the technological side of the product and contribute to the optimization and improvement of processes in customers’ projects.
JazzTeam implements CI/CD iteratively and painlessly, effectively overcoming learned helplessness and resistance of team members. 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.
In IT product development, we rely on OOP, various design patterns, recognized architectural paradigms and integration approaches, it 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 professionally apply best practices and approaches to development and testing, such as Model Driven Development, Test Driven Development, Data Driven Testing. By using the best engineering approaches, we create stable, scalable and easily maintained IT solutions. From the very beginning, we implement CI/CD for making regular deliveries. Following the principles of eXtreme Programming, our developers create functionality with a logical architecture, easy-to-maintain and readable code.
When starting a complex task, our engineers always perform decomposition and estimation, which helps them to solve technology related problems gradually and cost-effectively. This approach allows us to provide a guaranteed result in time, and the customer – to be aware of the status of tasks and understand what he is paying for at the moment.
Continuous knowledge sharing and lifelong learning are a constant part of our culture. JazzTeam has developed a methodology for retaining experience and reusing it between projects. If any of our teams have questions or difficulties, the entire technological expertise of the company accumulated over many years of work can be used to solve them.
We have also created an effective experience transfer system with the help of reference projects, which transfer best development practices to engineers and help specialists to effectively dive into new projects.
JazzTeam has developed its own training program for Java engineers, QA engineers (including Test Automation engineers) and DevOps engineers. The unified IT education system allows to continuously enrich employees with new experience and effectively transform education methods and plans. The program is constantly updated according to up-to-date trends and standards. As a result, we can guarantee that the knowledge of our technical specialists meets the current requirements and demands of our customers.
JazzTeam applies its own project management culture and uses standardized and formalized processes. Our company instills this culture in every manager and encourages initiatives for its development and improvement. Due to competently structured, formalized 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 the team. The 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 control the team performance. This includes facilitating communications and setting up processes from our side. Our managers provide a high level of process management on a project, introduce necessary task tracking and test management tools, and apply best management practices for product development. As practice shows, this approach contributes to the improvement and efficiency of processes on a project and reduces the non-production costs of engineers resulting in cheaper product development for you.
When necessary and when requested by a customer, our managers timely begin escalation, including using the expertise of other managers or involving the company’s TOP management in the project. JazzTeam regularly holds weekly meetings for managers, at which specialists share insights and challenges gained on a project.
Thus, working with us, you get access to the management expertise accumulated over 10 years of company’s work.
In all our services we use flexible approaches: apply Agile philosophy and build processes according to Scrum methodology. Our managers adopt regular meetings and stand-ups on all projects, which significantly increases the level of team synchronization. We ensure the complete self-organization of the team through retrospectives, in which misunderstandings and problems arising in the team are promptly resolved. Regular demos of new functionality in front of the entire team facilitate a common understanding of the current statuses on the project.
At different stages of the project life cycle, customers may face difficulties, questions, and additional risks. Regardless of the type of rendered service, in such cases we always discuss and solve customers’ problems and share our experience. However, there are situations when customers need professional consulting service. Consulting can be combined with coaching and presence of our specialists in the customer’s office for a more in-depth audit and transfer of experience. Consulting is a highly demanded service in our company, which brings excellent results. The effect of such cooperation is not only an improvement of the technical side of a product itself, but also of the customer’s business in general: from teamwork organizing to increasing business profitability.
In the most difficult situations or at the initiative of the customer’s TOP management, our founder Dzmirty Harachka (providing IT consulting services as an independent expert, zmicer.consulting) gets involved in solving complex issues on a project.
JazzTeam provides a thorough and comprehensive service for the design, customization, development, and integration of IT products. We are intently focused on creating high-tech solutions to effectively achieve all of our customers’ business goals and will actively participate at every stage of your projects.
We create scalable, stable products that customers can easily maintain on their own with minimal additional effort. Our team initially provides a high level of code coverage with easily extensible automated tests, in addition to creating all the required documentation. We will also include manuals on the use of our systems. The IT solutions we develop have a modular architecture and loose coupling of components, which allows us to ensure the effective implementation of new product features.
We develop and optimize various IT solutions for specific customer needs, which leads to the constant improvement of processes and increase of business efficiency. The service also includes various customizations of out-of-the-box solutions, including Open Source.
Our service includes application reengineering using the best and most up-to-date development practices. During system modernization, we evaluate the state of a product in terms of the architecture, the technologies used, and processes executed, and propose a variety of options for further code development. Before we start manipulating the codebase, we always try to create the necessary Unit and Data Driven tests to control the stability of the system during subsequent changes. All problems found are covered by Unit tests to prevent the recurrence of any fixed bugs. By doing so, we ensure regression testing of our fixes in all versions of your product, making the refactoring process more stable.
Due to our engineering approach, we professionally refactor complex, hard-to-maintain code and ensure an optimum level of reuse of developed components. All this reduces both the cost of product support and the involvement of new specialists on a project.
Our company also provides cloud architecture development services, integration with cloud services of Amazon, Windows Azure and other PAAS providers, and migration of your applications between cloud providers. If using the Cloud doesn’t fit into your privacy requirements, we can organize scalability by clustering on your servers.
JazzTeam has unrivalled experience when it comes to developing integration applications. When creating solutions such as these, we use the company’s collective expertise to build the architecture of complex IT products. Our specialists professionally design extensible, easily integrated (including plugin) architectures, and 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 applying of the MuleESB integration platform, and when necessary hold pass the «MuleSoft Certified Developer: Integration and API Associate» certification. Over our many years of working with MuleESB, we have gained extensive experience in creating commercial Mule connectors.
Our team has expertise in integrating various applications with platforms such 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. It is very often the case 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 perform this research every day for 1 hour a day, which in the end leads to excellent results. Practice shows that without getting hung up on one problem, a solution can be found faster. The application of this practice allows performing effective research within a limited budget.
We have substantial experience in technological research, effectively work on projects where a customer doesn’t yet have a clear idea of the ways of implementing specific solutions to achieve a business goal. In such cases, 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 a customer with a detailed expert analysis, estimation, architecture or prototype of the future product.
After completing a product, a customer may have new ideas for changing or improving the system according to current needs. Due to our approaches 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 embed Continuous Integration and Continuous Delivery into the project workflow. For continuous controlling of the system stability, our team professionally implements processes that allow prompt influencing of the product quality, and provide the customer with the necessary test management tools.
As part of this service, in addition to creating new functionality and fixing bugs in the application, we also maintain automated tests, create the artifacts required for manual testing, implement CI/CD, and work through technical debts. All of this allows us to effectively develop and modify the product. We also accompany the developed system with the necessary documentation describing its work, create installation and operation manuals.
Problems related to the technical side of a product (such as non-scalability, poor quality, unstable releases) can lead to additional risks that negatively affect profitability and business development. The creation of a strategy for such problems resolution requires considerable managerial and technical experience. In such a situation, a business owner needs the help of specialists with an independent view of the specific situation and the project as a whole, who can offer the most effective and safe ways for getting out of the situation.
Our company solves various problems related to the technical side of a product:
Working with us, you will not only get a strategy to solve these problems, but also the services of a personal manager who will manage the process of implementing improvements in your company. In the most difficult situations or at the initiative of the clients’ top business managers, our founder Dzmitry Harachka (also providing IT consulting services as an independent expert, zmicer.consulting) gets involved in solving complex issues on a project.

While working on a project, we always offer new ideas and solutions which can bring additional value to the customer. In addition, you can get professional advice from our founder on improving business processes and the technical side of projects.
You can begin working with JazzTeam from one service and, after making sure of the effectiveness of cooperation, add other types of services in the future. This practice is often used in cases where customers have a negative experience of working with a service company or concerns about delegating improvement of the technical side of a large business to an unfamiliar company. For example, on one project, a customer asked us for advice on how to improve the product development process. After a series of consultations, in addition to solving the main issue, it became evident that there was a need to eliminate technical debts (such as implementing CI/CD, writing Unit tests, covering the UI part with autotests). Our team proposed the customer to add additional services to be able to solve the main business challenge — scaling the product and bringing the company to the new level. The customer agreed to include working on the technical debt in the plan, and our team successfully completed these tasks. Such fruitful cooperation inspired the trust of the customer, as a result, they initiated the involvement of our developers in the project for further development of the product functionality.
Working with JazzTeam, you choose the degree of your involvement in a project: from receiving detailed statuses from our managers to participating in daily stand-ups with the whole team and retrospectives at the end of iteration. Professional approach to our work allows us to steadily make high-quality software deliveries, achieve goals within the stated deadlines and keep the team’s productivity at a high level throughout the project.
A value-based approach and continuous use of best practices by engineers and managers significantly reduce product development costs. Below we will tell you about 5 approaches used in our company, which save the project budget, improve the product quality, and simplify its further support.
During the first iterations, our specialists perform analysis, design the product, create the necessary schemes and diagrams, and only after reaching a common vision with the customer, they begin writing code. In this case, an important step is the creation of an MVP – minimum viable product, which allows us to verify the hypotheses generated during the design and requirements collecting. This strategy saves a lot of money in the future: it allows implementing only the necessary functionality and fully meeting customer's expectations. A product created by our engineers brings real business value and doesn’t need constant changes and rewriting code from scratch. Thus, competent design can save the customer’s time and budget.
Early implementation of CI/CD provides a lot of opportunities for budget saving:
Bugs in software at the production stage can result in huge costs for business. So, it is very important to constantly and timely perform comprehensive testing to ensure the stable performance of a product. With tight deadlines and frequent software updates and developments, it is difficult to organize a thorough quality control with manual testing. The solution is test automation.
Test automation is an essential and integral part of continuous integration allowing to stabilize product performance and save time and money for checking its quality. It is the most effective solution for identifying mistakes at all stages of software life cycle and organizing regression testing.
Due to the implementation of autotests, a product owner can make sure at any time that the key functions of the system work properly and avoid huge expenses on manual quality control and lengthy product stabilization.
For quality assurance, we synchronize sets of test cases for manual testing and for automation and automate only the number of test cases that are really needed. This saves a lot of money on creating and implementing autotests.
Complex IT solutions (e.g., knowledge-intensive products, data processing applications in the telecom sphere) often require checking a large number of input and output combinations. Creating tests for each type of data can be too time-consuming and require big expenses for the work of a quality assurance specialist. This issue can be resolved effectively with the Data Driven Testing approach based on comparing a set of input parameters with a reference result or state. An important advantage of a well-designed DDT is the possibility to enter input values and a reference result in a convenient form for all project roles: engineers, manual testers and even Product Owners. It is possible to significantly reduce the cost of product testing by delegating the task of increasing the data set, for example, to a manual tester. With the implementation of DDT, a test written once can be used many times and will allow receiving a huge number of different data combinations. Therefore, in the case of bugs it is enough to enter a new data set without the need to create an autotest from scratch, which saves a lot on product testing.
We have expertise in this field, professionally implement this practice, which allows us to save the budget for testing while maintaining high product stability.
Professional management and aligned processes help to avoid a variety of risks. JazzTeam managers always analyze possible risks, initiate their joint discussion with a customer and develop effective response strategies.
Proper communication management plays an important role in preventing problems related to customer dissatisfaction with the end result. Arranging regular meetings, demonstrating the results of the work performed, and constant feedback contributes to achieving a common vision resulting in a product that fully meets customer expectations. Such a result does not require additional investments and changes and certainly achieves the goal.
JazzTeam manager monitors the team’s progress and productivity, helps specialists to develop realism in task assessment and awareness of the impact of an individual module on the entire product performance. This helps to avoid the risks associated with estimation and delayed releases. Effective risk management in the long run can prevent enormous monetary costs.
