Rockstar🎓
Top SchoolBirkir Guðjónsson is a founder and seasoned software engineer based in Reykjavik with 15 years building full-stack and mobile solutions across TypeScript, React (web and native), GraphQL, and C++. He blends hands-on engineering—from low-level C and assembly on vintage hardware to modern React Native/iOS integrations—with product-minded architecture and project leadership honed as Technical Director at ueno. and now leading Enum. His open-source contributions span a GraphQL CMS he maintains, impactful TypeScript/typing improvements in react-three-fiber, and native navigation and CarPlay features for React Native, showing depth in both platform UX and developer ergonomics. Comfortable in both frontend and backend domains, he often surfaces non-obvious improvements like editor integrations (Ace.js) and refined type definitions that boost long-term maintainability. Trained originally with practical marine engineering and electrical/mechanical foundations, he brings a hardware-aware perspective to software system design.
