About

I'm a mobile-first principal engineer focused on building high-performance, user-centric mobile applications using React Native. I've worked across fintech and product-led companies, shipping solutions that balance performance, design, and long-term maintainability from early MVPs to large-scale production rollouts. My experience includes being the first to integrate React Native modules into legacy Android applications at Foodhub, improving performance and navigation in production apps at Divisions Maintenance Group, and enhancing user onboarding through seamless SDK integrations at Stanza Living. I enjoy working in collaborative, fast-moving teams, taking ownership of complex mobile problems and delivering solutions that scale reliably to thousands of users. I care deeply about code quality, architecture, and user experience, especially in environments where performance and correctness matter. Always interested in conversations around mobile architecture, platform evolution, and building products that last.
