Rockstar🎓
Top SchoolJohnny Lee is a software engineer with 12 years of experience building reliable systems at scale, currently contributing to Google from California. His background spans startups and enterprise environments, including multi-year engineering roles at Yelp and Global Aerospace, and a CS degree from UC Berkeley. He pairs cloud-scale software experience with hands-on embedded and IoT work—authoring control firmware and I2C menus for an open-source low-cost ventilator project that experimented with pressure and flow sensors. Known for adapting software across hardware platforms, he brings both systems-level thinking and practical prototyping skills to product development. Colleagues describe him as a pragmatic problem-solver who moves fluidly between firmware, services, and product-focused engineering.
