We worked with QAwerk on a new mobile app. They develop test plans, continue to do regression testing, and are also developing automated test coverage. I was really impressed with the depth and thoughtfulness of all the work, and even giving feedback on the app functionality itself. QAwerk has been very responsive to requests—I'm not sure when they ever sleep! The team is very clear and organized with managing the overall project and communication. Highly recommend!

Pablo Alba Chao
I worked with QAWerk’s team during the build out of Union54's card issuing API product, where they supplied manual and automated test engineers. The team were diligent, skilled and enthusiastic about the project, always willing to go the extra mile. The product quality was excellent as a result of the team, with 99% of bugs or missed requirements caught well before they hit the production system. And this, despite the ongoing issues faced by Ukraine where the resources were based. Would thoroughly recommend the team and wouldn’t hesitate to use them again.
