Product Engineer · AI Engineer · Founding Engineer
I design, build, and ship AI-powered products end to end — solo.
4 shipped iOS apps · 2 production SaaS platforms · 14+ AI microservices
I build and ship consumer iOS apps and AI-powered SaaS platforms with React Native, Expo, Next.js, TypeScript, Python, and Docker. I own every layer of the product lifecycle: product vision, UX/UI, system architecture, AI pipelines, CI/CD, deployment, App Store releases, monetization, analytics, and legal. I use AI-augmented workflows to move fast, but I am accountable for the production result.
