Jason Booth is a game-focused software engineer with 17 years of professional experience and over 20 years developing games and graphics, now specializing in client-side architecture, shaders, and real-time rendering. He blends mobile front-end expertise across iOS, Android, and React Native (Swift, Kotlin, TypeScript) with deep game-technology roots from Bioware and Warner Bros to indie tooling and Unity/Metal work. At OfferUp he led significant ad SDK refactors and native integrations that improved performance and monetization, and has shipped custom image caching, layout, and visibility systems that materially improved app UX. His open-source contributions include enhancements to the well-known cocos2d-objc framework (experimental Ribbon/MotionStreak work) and Unity vertex-paint tooling, reflecting a practical flair for visual effects and mesh/mesh-UI tooling. He’s comfortable as a solo engineer or senior team lead, with a track record of turning complex graphics and media problems into production-ready, performant solutions.
