What I'm looking for

I'm looking to lead frontend work on scalable, high-performance products where I can improve user experiences, collaborate closely with teams, and build maintainable React applications.

I've led frontend development for Bluebulb's cross-border payouts web application, using React, Redux, and Vite to support scalability, security, and regulatory compliance. I reduced initial load times by 40% through lazy loading, code splitting, and efficient state management.

At Dot, I built business banking workflows and interactive data-visualization dashboards used by more than a hundred businesses. I also led a high-volume loan application used by over 1,000 agents, improving adoption by 20% through RESTful API integration and low-bandwidth performance work with PWA, IndexedDB, and caching.

I've improved mobile performance and product loading times through code splitting, media optimization, automated testing, and maintainable frontend architecture. At Muzzlab, I helped launch an online education platform and reduced average page load time by 30% while improving homepage SEO.

I enjoy collaborating with design and backend teams, reviewing code, sharing frontend best practices, and delivering reliable UI experiences that meet business goals.
