What I'm looking for

I’m seeking senior frontend roles where I can lead UI/architecture, deliver accessible high-performance user experiences, mentor teams, and ship AI-enabled product features.

I am a Senior Frontend Engineer with experience building and scaling high-impact web applications for leading fintech and AI-driven creative platforms, specializing in React, Next.js, and TypeScript. I deliver user-centric features, optimize performance, and drive engagement while championing accessibility, code quality, and collaborative cross-functional work.

At Runway, Cleo, and Chime I’ve integrated generative AI into UIs, scaled products to millions of users, improved load times and reliability, and mentored engineers while establishing design systems and testing standards to accelerate launches and global usability.
