Summary
👤
Senior🎓
Top SchoolDavid Jeske is a seasoned software engineer, founder, and angel investor with 18+ years building and scaling high‑traffic backend systems—from founding Neotonic (acquired by Google) to directing engineering for Google Groups, orkut, and Sign‑in at Google. He blends hands‑on systems work (early career Voodoo graphics drivers, Python/MySQL performance tuning, and experimental storage like StepsDB) with leadership of large teams responsible for billions of pageviews per day. As a private investor and advisor he has backed and guided startups including Asana and RethinkDB, while shipping consumer products such as the iOS game King of Draw. An active open‑source contributor, he’s improved cross‑platform input and windowing behavior in the widely used OpenTK library, reflecting deep familiarity with low‑level platform quirks. Based in Park City, he pairs a pragmatic, customer‑centric design sense with a history of rapid, high‑risk integrations (egroups/onelist) and mentorship across engineering organizations.
