Andrey completed a follow-on mathematical solution project quickly and accurately. He is great to work with.

Andrey did a great job with a small, but mathematically complex program. His response was quick and I will work with Andrey again.

Plasticworks says,

Andrey and his work has been professional and timely. There have been some communications issues between us (timezones too!), and the project description was not detailed enough to come to a full resolution of the intended problem (my fault). I intend on reviewing the source code and perhaps working with Andrey in the future to complete the project.

I have been happy with Andrey's services to this point in the project and look forward to the final product and beyond.
