Bryan Lee

Led Engineering at DraftKings, Co-founded Two Companies

I am a seasoned software engineer with extensive experience in 0-1 full-stack development and team leadership. Throughout my career, I have championed efficiency, automation, and best practices to deliver high-quality products and services. I co-founded and developed two successful restaurant platforms that have served 20,000+ paying customers and processed $2MM+. I also led the engineering at various company sizes from pre-seed to public often overseeing projects being built from 0-1. I take pride in delivering seamless and smooth real-time user experiences and upgrading outdated and inefficient practices and processes.
