PROFILE

Xavier Stouder

Worked across core Node.js and related repositories to deliver robust backend and developer tooling improvements. In nodejs/node, enhanced child process stability by making OS signals constants immutable using JavaScript, and clarified build documentation to reduce onboarding friction. Developed automated codemods in nodejs/userland-migrations, leveraging AST manipulation and TypeScript to migrate Mocha test suites to the native Node.js test runner, streamlining modernization efforts. Improved CI/CD security with trusted publisher workflows via GitHub Actions. Addressed schema management bugs in liquibase/liquibase using Java and SQL, and refined linting accuracy in biomejs/biome through targeted Rust and JavaScript analysis, emphasizing maintainability and test coverage.

Mar 1, 2026

March 2026: Focused on clarifying the build/test workflow in the nodejs/node repository to reduce user confusion and support overhead. Implemented a documentation update that explicitly states that make test and make test-only do not run linters, aligning docs with the actual build process. The change improves developer onboarding and reduces misaligned expectations about linting during test runs.
