While I was working with Valentin on this project, I really enjoyed. He knows what he wants from the project, but also follows advice and accepts feedback. That way, we were able to finish things in an efficient manner. I will gladly work with Valentin in future and would highly recommend him.

Valentin is a very talented, hard working and industrious person. He is so passionate about security and teaching other people new things. I can’t wait until the next time I get to work with him on this project, and I hope that we’ll continue to make awesome things in the future.
