Summary
👤
Senior🎓
Top SchoolLiam Tarpey is a Senior Frontend Engineer with over a decade of experience building scalable web platforms, design systems, and performance-focused architectures from London. At Busuu he led large infrastructure overhauls—consolidating multiple apps into a monorepo, migrating to Vercel, and automating 1,200 CMS pages—delivering measurable wins in CI speed, onboarding time, and content team efficiency. He pairs deep hands-on expertise in React, Next.js, TypeScript, Contentful, observability and CI/CD with product-minded delivery, improving Lighthouse scores and core web vitals through full-stack caching and metadata tooling. Liam has a track record of systematising engineering practices—introducing RFCs, frontend guilds, shared tooling and a private NPM design system—that reduced duplication and accelerated cross-squad delivery. Equally comfortable shipping code and mentoring teams, he has scaled initiatives end-to-end from real-time classroom products to a major platform redesign that boosted engagement and conversions. A former sole frontend builder for startups and agency work, he brings pragmatic craftsmanship and a knack for turning operational problems into long-lived platform improvements.
