Summary
🤩
Rockstar🎓
Top SchoolBob Ippolito is a seasoned CTO and serial co-founder with 24 years building high-throughput, internet-scale systems—from multi-gigabyte databases and ETL at Mochi Media to game publishing and iOS virtualization startups acquired by larger firms. Based in San Francisco, he blends deep systems and networking expertise with hands-on development across Python, Erlang, Haskell, JavaScript and Rust, and has contributed to prominent open-source projects including CouchDB and mypy. Bob has a track record of shipping pragmatic, concurrent server architectures and developer-facing tools, plus front-end and mobile integrations demonstrated in React and Lexical contributions. He also invests time in community and education, serving on the board of Mission Bit and teaching coding to Bay Area high school students. Not obvious from titles: he routinely dives into low-level bug fixes and performance tuning (e.g., memory leak fixes and end-to-end security tests) while mentoring teams through acquisitions and product transitions. His mathematical background underpins a wide-ranging curiosity that spans embedded kiosks and RFID systems to modern typed-language toolchains.
