About

I build frontend systems that handle real money and real users. For 7+ years, I have developed web and mobile applications across fintech and large consumer platforms. My focus is performance, security, and clean architecture that lasts. At Wing Bank, I build secure loan systems and real time financial dashboards used in production. I translate business and compliance requirements into reliable React and TypeScript applications. I also work with AI assisted development to speed up engineering workflows, prototype faster, and review AI generated code while maintaining production quality. Previously, I led cross platform mobile development with React Native, shipping production apps to the App Store and Play Store while improving performance and reducing technical debt. Strong in: • React, TypeScript, Next.js, React Native • AI assisted engineering workflows • Secure API driven UIs • Performance optimization • Real time systems with WebSockets • Testing, CI, and frontend security I enjoy building systems that need to be reliable, scalable, and trusted by real users.
