What I'm looking for

I’m looking to bring AI-forward engineering practices—like GitHub Copilot and LLM-assisted code review—into a high-growth product team, with room for ownership while building high-performance, well-tested frontend systems.

At Synchrony Financial, I’ve built and standardized a centralized TypeScript types repository adopted by 5+ applications, cutting type-related bugs by 25% and aligning shared interfaces across teams.

I’ve improved Core Web Vitals and Lighthouse performance, moving scores from 50 to 90—shrinking page load time by 35% and strengthening user engagement and SEO. I’ve also written 200+ unit and end-to-end tests with Jest, Cypress, and Cucumber to reach 95% coverage and reduce production bugs by 40%.

Earlier at Synchrony Financial, I led micro-frontend architecture across 3 teams to enable independent deployments and reduce release cycle time by 20%, and I partnered with UX, backend, and Product to deliver a reusable component library. I’ve also used GitHub Copilot and LLM-assisted code review (ChatGPT, Claude) to accelerate debugging and speed up code reviews without sacrificing code quality.
