Summary

Rockstar🎓
Top SchoolSimon Sinclair is a founder and senior front-end engineer with 12 years’ experience building performant, user-focused web applications from the BBC’s global news platform to fintech at Checkout.com. He led major refactors and front-end rewrites that materially improved SSR performance, Core Web Vitals, and reduced client-side JavaScript and third‑party dependencies. At Qogita he combined hands-on TypeScript/React development with hiring and mentorship, improving hiring outcomes and developer quality through take-home exercises and tooling. As a contributor to the BBC’s open-source Simorgh project he implemented and tested UI components and media features across AMP and canonical pages, demonstrating deep expertise in Next.js, React and testing frameworks. Now splitting time between scaling Food Services House and senior engineering at Checkout.com, he blends startup founder mentality with production-scale engineering discipline. He’s as comfortable stabilising 24/7 critical systems as he is iterating on developer experience and front-end architecture.
