Summary
🤩
Rockstar🎓
Top SchoolWill Binns-smith is a JavaScript-obsessed fullstack software engineer with 12 years of experience building performant web platforms and developer tooling from San Jose. He currently ships core web and bundler features at Vercel after leading Parcel 2 replatforming and bundling architecture at Atlassian and contributing front-end infrastructure at Facebook. His work spans build systems, dev servers, HMR/source-map fidelity, CSS module handling, and Flow type definitions—reflected in notable open-source contributions to Parcel, Turborepo/Turbopack, and Next.js. Will combines deep front-end instincts with low-level build-system expertise, often improving developer experience and production performance in equal measure. He’s comfortable moving between product code and infra, from React feature work and RSC/HMR edge cases to Rust-backed build tooling integration. Beyond shipping features, he’s driven measurable platform improvements like asset deduplication and component-performance measurement systems.
