Senior🎓
Top SchoolTom Sun is a product-focused founder and technical leader with 11 years of software engineering experience, currently building AmpUp in the EV charging space out of San Francisco. He moved from high-frequency and large-scale engineering roles at Jump Trading, Goldman Sachs, Yahoo, and Twitter into machine learning work and ultimately entrepreneurship, giving him a rare mix of systems, data, and product instincts. At AmpUp he applies practical, shipping-oriented engineering to solve real-world EV infrastructure problems, combining deep backend experience with a founder’s eye for go-to-market fit. A YC alumnus (Startup School and W19 batch), he pairs startup rigor with enterprise-grade engineering discipline. Colleagues would note his trajectory from quant/infra teams to consumer-scale platforms and now hardware-adjacent mobility products, reflecting an ability to translate complex technical tradeoffs into usable products.
