What I'm looking for

I'm looking to build high-quality web and mobile products where I can own end-to-end delivery, improve performance and architecture, collaborate closely with clients and teams, mentor engineers, and scale practical AI-assisted development.

I've shipped React and React Native applications for InvoCare, NFHS Network, Birdseye Security, Barnardo's, and QwikCut. At InvoCare, I contribute across a 25+ repository suite, coordinating contracts, authentication flows, and performance work while embedding Claude Code and GitHub Copilot into delivery.

I've built video streaming and clipping, reusable UI systems, real-time functionality, mobile features, and automated tests. I improved Birdseye Security's initial page load time by 30%, maintained roughly 85% unit-test coverage for NFHS Network, mentor junior teammates through reviews, and present sprint outcomes directly to clients.
