High quality

We build reliable software. Our dedicated team of testers controls the behavior and performance of all products. We follow Continuous Integration practices that allow our teams to move fast while keeping high-quality standards that are checked automatically.


Custom software development doesn’t need to break the bank. Due to the somewhat lower cost of living in our part of the European Union, our rates are lower. However, our engineers still boast high education, work ethics, English skills, and advanced programming abilities.
