Worked on the ocaml/opam-repository, delivering a major release of Catala Language 1.1.0 focused on enhancing developer tooling and streamlining onboarding. Developed and integrated improvements to the Language Server Protocol (LSP) and introduced a new code formatter, implemented across catala, catala-lsp, and catala-format components. Leveraged OCaml and full stack development skills to ensure end-to-end traceability from commit to release, emphasizing clear versioning and maintainability. The technical approach centered on improving code formatting reliability and developer productivity, resulting in a more robust developer experience and facilitating easier contributions to the Catala ecosystem through improved language tooling and documentation.
