Summary
🤩
Rockstar🎓
Top SchoolDav Yaginuma is a seasoned Staff Software Engineer and three-time founder with roughly three decades of experience building and scaling products from MVP to multi-hundred-million-dollar valuations. He combines hands-on engineering (notably early hit iOS apps with 10M+ downloads and high-grossing mobile titles) with leadership running teams up to 40 engineers and directing product and engineering at VC-backed startups. Dav excels at turning founder‑stage codebases into maintainable, testable systems and has repeatedly shipped fast MVPs across Ruby, Objective‑C, JavaScript and Java while picking up new languages easily. His background spans product, ops and machine learning (including contributions to a word2vec implementation), and he currently works on iOS CarPlay and Siri/Language Technologies at Apple. Comfortable in diverse, often remote-first teams, he prefers roles where leadership values multidisciplinary collaboration and long-term code quality. An entrepreneur at heart, he’s raised capital, led acquisitions, and still enjoys dogfooding systems by running real warehouse operations to validate his logistics software.
