"I couldn't quite believe how lucky I was to meet Viktor. He approached me as he had some spare time and managed to get the job done super quickly. The quality of the code was absolutely outstanding and he even managed to find a bug in the existing code which an auditor couldn't - the bug was so severe that we ended up having to recreate the token from scratch so I am extremely thankful we met him - he's an excellent asset to Upwork and we will definitely be working with him again in the near future."
