When I moved into building the full game and all the underlying systems, I brought him on for that as well, and he’s been outstanding. He really knows Unity at a high level, especially on the systems side. He handles complex work with confidence, learns quickly, and consistently steps up to tough challenges instead of avoiding them. On top of that, he’s a pleasure to work with. Polite, reliable, strong work ethic, and always ready to go. I trusted my gut when I chose Sang from a strong group of candidates, and I have zero regrets. It was the right decision. I highly recommend him to anyone looking for a skilled and dependable developer." — David Eagle
