Before working with Dmitry, our application had no test suite due to time constraints. I always knew we needed tests, but Dmitry helped put things into action. He created a set of unit and integration tests that mean we can now make code changes with confidence. I found Dmitry's critical thinking helpful. An example of this was his encouraging us to use Continuous Integration (CI). Now our tests run automatically each time we push any changes to Github. I definitely recommend Dmitry’s Technical Debt Rescue service for anyone looking to reduce development time by prioritising testing and/or refactoring. Dmitry is a very careful coder and I could definitely trust in his work.

Dmitry's services are excellent. Dmitry helped us refactor our application and his knowledge of Ruby and Rails architecture is excellent. I highly recommend Dmitry to any project or business that is finding their development efforts slow or hard due to a large amount of technical debt. His approach is deliberate and informative, and all members of the team will benefit from his thorough explanations and guidance.
