Making a difference in open-source
summary
A developer gets paid by G-Research to work one day a week on F# tooling and refactors phantomus, releases phantomus v5 (Sept) and grows a maintainer team so the formatter reliably runs on real codebases. Contributions fix the F# parser and add reference assemblies and a parallel type‑checking flag that land in .NET 7, measurably improving large-solution build times. Work also touches Ionide/Rider integration, tests-first formatter rules, and onboarding that turns reporters into co‑maintainers.
