PROFILE

Michael Kozono

During September 2025, Masahiro Kozono enhanced the gitlabhq/gitlab-shell repository by delivering the Geo Proxy Direct-to-Primary Default feature. He removed the legacy geo_proxy_direct_to_primary feature flag, refactored uploadpack and read flows, and updated tests to support the new default behavior of routing Git over HTTP directly to the primary repository. Working primarily in Go and Ruby, Masahiro focused on backend development and version control, ensuring the codebase was streamlined and maintainable. His work included cleaning up deprecated code paths, updating release documentation, and validating changes through CI, ultimately reducing operational risk and simplifying the Geo proxy workflow for future releases.
