Worked on enhancing package management and testing reliability in Julia projects, focusing on JuliaLang/Pkg.jl and JuliaRegistries/General. Upgraded the StaticArrays dependency within the Pkg.jl test suite to version 1.5.20, ensuring tests accurately reflect current package behavior and improving CI stability. In JuliaRegistries/General, implemented a compatibility constraint for StaticArrays.jl in Compat.toml, preventing errors on older Julia versions and supporting downstream stability. Leveraged skills in dependency management, version control, and Julia to maintain repository hygiene, document changes, and proactively address compatibility issues, resulting in more robust test infrastructure and smoother package experiences for users across Julia versions.
