QA from the very beginning

Professional support from day 1

We start Quality Assurance activity in the specification writing phase by reviewing and giving feedback to the editor of the functional specification. Our Senior developers, Testers and Software Architects provide their input in terms of planning.
We prefer jump in even earlier stage with experienced Business Analysts who can help the client defining business ideas in the form of a software solution. Thus the expensive dead ends are avoidable.

Quick iterations

We follow the Agile approach, typically in two-week sprints, which enables the formulation and achievement of efficient sprint goals, as well as adds flexibility to change management. We support rapid testing cycles of the current version of the software with continuous integration methods.
As a result, the client is able to try out the system in its current state from the very beginning of the development.

Full transparency

Cloud based task management and the reporting tool (Jira) provides a full view of the hours spent on tasks in the given development cycle. It solves the joint editing of the Backlog, as well. The test cases and the results of their runs are also transparent to our customers ( we use TestLink software). This enables the customer to feel like that we are part of the internal team throughout the software development process.

Future-proof solutions

Our experienced test engineers automate the test run (with our own, state-of-the-art, Selenium based solution) for the test cases of stable functions. This way, it is possible to implement new functions under stable operation of previous functionality.
Several members of the QA team are ISTQB Certified Testers.

Long term maintainability

We are rigorous in using industry standard solutions to keep options open.


We are experts at preparing improvable software. The key to facilitating the integration of future changes is that we pay careful attention to software architecture and quality from the outset of the project.
This allows adding new features to the software in every phase easily and sustainably.


Our experienced architects plan the system in a modular fashion and, by using a code review mechanism, keep the functionality in the appropriate software layers (generally following the MVC model). In case of restructuring becomes necessary, we achieve it through code and modul refactoring.
This way, changes only required at the relevant moduls of the software, and even connecting new ones can be easily accomplished.

Code quality

Code analysis is automatically run both on the front and backend codebases. The result is then used to improve code quality in daily development. We keep Unit test coverage of common components close to 100%.
Getting code quality right from the very beginning means quicker, easier changes in the future and lower overall costs.

Extensive experience

We are Java Enterprise Edition experts with experience deploying Java based projects since 2002.
With over 90 years of combined experience in Java development, our architecture and development team of nearly twenty-five experts is available to serve the IT and business needs.
If the development of a complete solution requires some unique and specific knowledge, thanks to our wide network of professional connections, we are able to involve additional specialists at any time. This guarantees that the developed solution is implemented with the highest level of expertise.

Up-to-date technologies

Keeping track of the most recent trends and technologies is one of the cornerstones that enables our team to deliver modern products of various levels of complexity.
Settled solutions of Java technologies extends the useful life cycle of the given software for long time.

Comprehensive service
