I’m a full-stack developer with 21 years of software development experience across multiple tech stacks. I’ve shipped production Flutter apps, built playable JS ads, Roku games, worked with FlutterFlow, Firebase, and Supabase, as well as game frameworks. I enjoy transforming product concepts into production-ready applications with strong focus on UX, performance, and long-term maintainability.
