Steve Coffey is a founder and full-stack engineer with 11 years of experience building web and mobile products from startup to scale. Currently a Member of Technical Staff at OpenAI in San Francisco, he previously co-founded and led engineering at Trava and served as a tech lead at Sonder, combining product instincts with hands-on delivery. His background spans front-end, back-end, and native mobile—early work at Barracuda included leading a mobile team for a 5M-user product and designing a cross-platform sync engine.
