He built an AI agent that won the 2023 Microsoft Global Hackathon, beating hundreds of other teams. He taught himself to code at 18 while circumnavigating the world. Eric thrives in the grind and delivers quality code, making him critical to building the high-performance, scalable integrations that customers expect from Arcade. Eric is also the largest “code detractor” at Arcade… and he’s damn proud of it.
