Summary
🤩
RockstarPeter Lenahan is a Senior Frontend Engineer with a decade of experience, based in Worcester, MA, and currently building front-end systems at Apollo.io. He specializes in modern React/Next.js and Preact stacks, GraphQL/AppSync integrations, build tooling and CI/CD, and has led product-facing projects from the att.net microfrontends and Zimbra X client to a Next.js account dashboard and eCommerce funnel work. He has a practical full‑stack streak—migrating backends to AppSync, implementing Stripe to cut subscription fees, and running A/B tests—while also driving significant performance wins such as a 66% reduction in critical bundle size. An advocate for reliability, he has contributed QA/test automation to the well-known redux-undo project, adding thorough unit tests for undo/redo and history navigation, which reflects a deep understanding of state management and maintainable front-end architecture.
