About

Contributor to GitLab's open source codebase since 2026.

What I work on

I pick up confirmed bugs and quick wins from the GitLab issue tracker and turn them into focused merge requests: a failing spec first, the smallest correct fix, and a changelog entry. Most of my work lands in gitlab-org/gitlab (Ruby on Rails), with additional fixes in Go (GitLab Runner, Terraform provider), Python (AI Gateway) and Terraform (GRIT).

Recent themes: merge request templates, blame and diff viewers, CI job token policies, SAST job configuration, rate-limit error handling, Geo replication pages, and hardening of the import/attachment pipeline.
