Vladimir Kovalchuk

With Vladimir, the results are very quickly achieved.

Successfully performs important functions.
Applying Java and Kotlin, it is a great opportunity to support any projects.

The project had to be closed because of the iron restrictions on my phone. The app is made and works on more new versions of Android. But in this way, unfortunately, it has no sense for me. Vladimir was a young man, trying to help and understand to the last. Responsibility and communicability at a high level.

Thank you for good work. Vladimir in connection. It works quickly, quality, even with its improvements that we did not hesitate to predict at the stage of the TZ setting.

Successfully set up the UTM melt processing feature that allows the mobile application to track traffic sources from the Play Market, now we are able to determine where users will learn about the application.

satisfied with work. It is worth noting that Vladimir even introduced a few moments that were not in the TZ. He has done additional work. He explained uncomprehensible moments and explained everything in detail. Some of the TZ moments were not implemented, but everything was immediately corrected. Therefore there are no problems. We will work further.

I did everything in the best way with a really high level of implementation of the project. I strongly recommend cooperation.

I highly recommend Vladimir as an experienced, erudited and proactive specialist. So it came out that this project had to work with the legacy code. Everything is done very well. In addition, I am grateful to Vladimir for the audit of the “high places” in the project.
We continue our work now.
