Rockstar🎓
Top SchoolBob Matcuk is a versatile Senior Backend Frontend Engineer with over a decade of professional experience and a lifetime of programming that began at age eight. He moves fluidly between front-end TypeScript/React work and back-end systems (Postgres, Node/Express, Go), having improved large-scale data flows and low-latency communications at companies like HEAVY.AI and OpenPhone. Bob has led cross-functional projects—from building A2P registration flows and a Temporal-based automation engine to architecting a performant call-view for half a million daily records—and is recognized internally for Postgres expertise. As sole engineer for a nonprofit, he shipped a Flutter mobile app and a PostgREST backend that achieved a 4.9 App Store rating, showing product-minded end-to-end delivery. He’s an active open-source contributor, notably enhancing HeavyDB’s web server and adding TypeScript typings to DefinitelyTyped, reflecting a blend of systems-level and developer-experience focus. Constantly curious and community-oriented, he tutors at makerspaces and brings a rare breadth of languages and platforms—from kernel drivers to GPU-accelerated analytics—to every role.
