BIO
Software engineer, computer scientist (M.Sc.) and entrepreneur. Problem solving and attention to details with big persistence is my passion. I led the tech team at Faze Clan before they went public at $1B valuation and was a key contributor of Plex at Ericsson - the core language that handles 25% of the world's 2G and 3G network communication. I created two successful open source repositories - automated testing repo that got 1.4k Github stars and now, GPT Pilot, which has over 22k stars.
