What I'm looking for

I seek senior/lead mobile roles where I can build secure, user-centric cross-platform apps, lead teams, and improve CI/CD and product quality.

I am a Staff Mobile Engineer focused on creating secure, high-performance cross-platform mobile applications using React Native and TypeScript. I have led development on major products including the MetaMask mobile wallet, delivering robust security, performant UI, and seamless dApp integration.

Across startup and enterprise environments I have built apps from scratch, implemented real-time features, offline support, payments, and CI/CD pipelines, and mentored engineers to improve team velocity and code quality. I combine strong problem-solving with business awareness to drive user-centered solutions.

I thrive in agile teams where I can own end-to-end mobile solutions, streamline releases with automation, and mentor colleagues while contributing to architecture, testing, and performance optimizations.
