Rockstar🎓
Top SchoolDuncan Healy is a seasoned software engineer with nine years of recent professional experience and a programming pedigree that stretches back over 30 years, from ZX81 beginnings to modern cloud and web stacks. He blends front-end contributions to notable open-source projects like Astro with backend and database engineering work on Supabase, including careful schema design and row-level security. Comfortable across systems—from Android and service workers to NoSQL and AWS—he breaks complex systems into manageable tasks and enjoys the small strategic gains that lead to robust solutions. His background includes roles from consultancy and product engineering to senior positions at Globalization Partners, and an eclectic past running an organic produce business and managing a self-built solar house project, which speaks to practical project management and resourcefulness. Duncan favors pragmatic innovation: applying lateral thinking to bring structure to data and processes while avoiding needless reinvention.
