  A consummate professional and always very knowledgeable. I'm grateful to have Yev helping me with my react-native project.

  Yev continues to be a great communicator and trustworthy partner, completing work tasks professionally and when promised. Being a developer myself, I've reviewed his code and can vouch for the high quality. I noticed that he even went a step above in some cases to clean up code which wasn't used. Most developers will just leave it because it's also not technically doing much harm, but the fact that Yev cleans it up is a sign that he's not most developers. He cleans it up because it's the right thing to do and reduces the technical debt of the code base over the long run. I'm glad I chose Yev.

  Very satisfied working with Yev. He adjusted his hours so that he's available during my work day in the US. He diligently and tenaciously worked through the weekend to solve a very difficult technical issue preventing the mobile app from accessing the network in the iOS emulator. He has strong react-native skills, quickly understood the requirements, and completed phase I very quickly. Looking forward to continuing the work in Phase II.

  I really enjoyed working with John. He is super efficient and even when I am busy, he would be able to solve problems on his own.

  I was looking for a freelancer to help fixing some issues and maybe working on some new features on my website. John did one amazing job working on the tasks I had outlined! He fixed the issues quickly and with great care and he worked on new features, too. It is just so great to have a freelancer who just works on the tasks without endless discussions about why things need to be done a certain way. He tried his best to understand the requirements (which were rather complex) to make sure to implement the code correctly. When I found a critical bug he stopped his work immediately and took care of the bug so we could be up and running. He's just a great freelancer to work with and I'd definitely recommend him to anyone! I'll definitely work with him again!
