Rockstar🎓
Top SchoolWojciech Biela is a seasoned software leader and founder with over a decade of experience building distributed SQL engines, big data products, and engineering organizations from the ground up. As a co‑founder and senior engineering leader at Starburst, he helped scale a small Trino-focused team into an enterprise-grade data platform used worldwide and led the Warsaw engineering site through multiple company stages. Hands-on technically, he has contributed to high-profile open-source projects like Presto and Trino—improving query engine statistics, JDBC behavior, and benchmark precision—so he combines deep systems expertise with product instincts. He has repeatedly built remote, cross‑geography teams, established hiring and engineering cultures, and transitioned into product management to better align engineering with customer needs. Now serving on a supervisory board and exploring what’s next, he’s open to ambitious technical challenges or another startup journey. A background in classical philosophy alongside an MS in software engineering hints at a reflective approach to technical strategy and decision-making.
