Summary
🤩
Rockstar🎓
Top SchoolArnaud Barré is a software engineer based in Paris with 10 years of experience building web platforms and developer-first tooling. He combines practical product work—shipping React/TypeScript apps and GraphQL backends at startups like Nabla and Carbometrix—with deep open-source involvement as a Vite team member and maintainer of React plugins. His contributions to Vite and related tooling show a focus on DX, HMR reliability, and build performance, while his work on oxc demonstrates fluency bridging JS and Rust for compiler/AST concerns. At Carbometrix he now applies that stack expertise (React, tRPC, Prisma, Postgres, GCP) to automate greenhouse-gas reporting, marrying developer ergonomics with climate impact. Colleagues would note his knack for fixing subtle runtime and serialization issues that improve both developer experience and system robustness.
