The customer testimonial about project: Xml2selenium – the JazzTeam Company’s product

"Since we release new versions of our platform on a monthly basis, we spent a lot of time on manual regression tests.

JazzTeam completely automated our regression test set and put up the required testing infrastructure for us. Their XML2Selenium framework enables our testers to implement new test scripts without any Java knowledge. The XML2Selenium reports help us to quickly assess bugs and problem areas in our platform. The integration with BrowserStack allows us to test on all combinations of browser and OS that we want to support, without any extra effort.

JazzTeam provided excellent support and swiftly responded to all our questions and problems."

I was particularly impressed by their work attitude, keen problem solving and, not in the least, by their great team spirit."

JazzTeam staff met us halfway, all the contentious issues have been successfully overcome. JazzTeam developers pay much attention to communication and clearly defined Agile processes.

Product company
Services in the field of estimating and managing the implementation cost of large-scale industrial projects, Netherlands

"We have been developing a software product in project management for large industrial enterprises. It is important for us that our application is constantly evolving, becoming more user-friendly. One of the significant improvements was the ability for multiple users to work simultaneously with the same document. To solve this complex and non-trivial task, we have involved JazzTeam company.

It was pleasantly surprising that JazzTeam engineers nearly independently sorted out and immersed in large amount of existing code without any additional Knowledge Transfer sessions visiting our office, video conferences were enough. Based on new technologies, the engineering team developed a solution that is compatible with the existing application architecture. This decision formed the basis of a new framework, which has almost been applied to all parts of our application.

During the work, JazzTeam development team applied various engineering practices (architecture design, Unit testing, Continuous Integration, Research and Development), set up testing process of the framework which was being implemented.

The cultural values match, the involvement of JazzTeam engineers into the project and focus on the result, well-established internal company processes of development and management, a streamlined and well-functioning educational process of specialists training for the project allowed us to maintain constantly a good and stable pace of the team’s work throughout the entire period of cooperation, which has been lasting for over 3 years. Separately, it should be noted that the founder of the company is always open to dialogue and can be contacted for any business issues.

We are satisfied with our partnership and recommend JazzTeam company as a reliable partner."

"The main project task of JazzTeam engineers was to develop the new functionality of the web application intended for maintaining regulatory and reference documentation of a clinical diagnostic laboratory.

Vadim Kastritsky
CEO, VironIT, Custom software development company

"The task of this project for JazzTeam members was rather complicated, that is the expansion of the game functionality, which included immersion in the existing for more than 10 years implementation. For development it was necessary to study and take into account the game rules, which are listed in a large six hundred page manual. The task is complex, and requires a serious architectural approach and high qualification of the developer. And JazzTeam members coped with it at the proper level.

I note that the working process of JazzTeam company fully corresponds to the spirit of Agile. The team actively offered solutions for implementation of complex technical issues and also warned in advance about possible risks. We are truly grateful to the staff of JazzTeam."

"I would like to commend the work of the JazzTeam team members on our project during solving complex problems, their serious and thoughtful approach to problem research, their active participation in the architecture update, their advice and assistance to our employees. It is also worth noting that the guys offered non-trivial solutions and were always in touch.

Separately, I want to mention the constant JazzTeam’s managers involvement and efforts to support employees. In fact, it is quite a unique phenomenon, none of our other contractors have such participation from the management side.

We have already recommended JazzTeam engineers to our company colleagues. And if on our project the need for assistance arises again, it is likely that we will engage them once again, since there are no serious claims, and their code is good.

Good luck in all affairs!"

The customer testimonial about project: Monitoring and management system of state procurement for tender contract department

"We started the development based on a completely new technology combination for both us and JazzTeam: Java script client ExtJS 4 for the Alfresco Web services. Ours was an investment project with extremely short deadlines and exigent progress requirements.

The team has shown that it can successfully perform coping with the stressful conditions of our work process, which is characterized by very short sprints (1 week) and high requirements to the quality of each release (the need to install the updates at the customer's site after a couple of hours since the release). The result of the work was successfully presented to the investment directorate, and the objectives were declared achieved.

I would like to stress that we faced a couple of considerable challenges during the project, and those were dealt with constructively and with utmost professionalism. As a result, they were quickly concluded and, what is more, carried out important management decisions and process adjustments. I am profoundly grateful to all the participants, who, being apprehensive of the roots of the matter and showing professional work attitude, brought our cooperation to a really high level and provided a decent quality of the development by a geographically remote team."

Their ability to identify hidden problems and eliminate them quickly and efficiently. In my opinion, this is a natural component of any project in which JazzTeam participates.

Stable and confident work of the team, reasoned actions, clearly posed questions - all that makes JazzTeam the professionals in their field.

I particularly wish to commend the management team, which has set a high level of responsibility from the very beginning: they always not only listen to our requirements, but also hear them, and implemented everything exactly in the form that we need and that is the most important thing.

We would like to note that the team took a proactive approach and was results-oriented from the very first days of the project. The team's immersion in a new subject area did not cause any difficulties and was promptly done.

Agile methodologies practices, such as daily Scrum meetings, weekly sprints and the results presentation, were implemented in the project from the very beginning. This allowed us to keep all communications at a high level, to focus on the outcome, to respond timely to challenges and changes in external circumstances, to get over pitfalls and to adjust plans and processes.

All the works were completed in full compliance with the requirements and within the specified timeframe.

We wish JazzTeam success in its professional activities."

Product company
Services in the field of agricultural technologies

"We turned to JazzTeam to create a prototype, and during our cooperation we decided to work together on the development of a full-fledged version of the web application. We received not only the result that we expected directly from the development, but also assistance in organizing and maintaining the infrastructure, in consulting on development and testing. The team did not solve issues on the nose, they analyzed and proposed optimal ideas for implementation. We gained much advantage from choosing JazzTeam as a contractor to solve our business challenge.

I would also like to note the high level of professionalism: we had difficulties in understanding how to work with the team remotely, how to convey our ideas, because the application was developed from scratch, there were many unfinished nuances that needed to be discussed and implemented in the daily planning mode, but as a result, the guys did an excellent job by doing their work and always optimally solving all the difficulties encountered on our way.

We are satisfied with the cooperation with JazzTeam and plan to continue it in the near future. Surely, we recommend the team and the company."

German Sazonov

"We have had a productive and successful cooperation with the company "JazzTeam". The team showed itself proactively and responsibly. Consistently delivering high quality results. We can rely on them and be confident in the completion of the task. Responsible, communicative. A very important point - independent.

At one of the development stages, we faced a situation where we had to work under very tight deadlines. Individual requirements for the UI-part were clarified on the go and changes were promptly made. But even under these conditions, the JazzTeam proved to be very worthy.

We are satisfied with the cooperation and believe in its further continuation!"
