About

Senior Full-Stack Engineer and Engineering Leader with 7+ years in software engineering. Currently Head of Web Development at Group Link One, where I architect and lead the multi-tenant platform behind 5+ B2B AIoT SaaS products serving utilities, smart cities, OOH media, and fraud detection. My path started with 4+ years as a senior iOS engineer — shipping SDKs, consumer apps, and co-developing a patented IoT communication protocol. I transitioned into engineering leadership in 2024, building a team of 5 with 100% retention. I believe great products come from well-led, inspired teams.
