What I'm looking for

I seek remote roles focused on open-source backend engineering, Git and CI/CD reliability, collaborative OSS governance, and opportunities to mentor contributors while improving tooling and repository integrity.

I am an open-source developer and backend engineer with 3+ years contributing to, maintaining, and reviewing code across active public repositories. I specialize in advanced Git internals, repository recovery, and restoring broken histories without data loss.

My work spans backend development in Python, Go, and Node.js, CI/CD pipeline design with GitHub Actions and GitLab CI, and containerized deployments using Docker and Kubernetes. I routinely perform deep code reviews, optimize contributor workflows, and document RFCs and contributor guidelines.

I also support AI/LLM model evaluation and prompt testing, manage secure dependency updates, and collaborate asynchronously with global teams to improve OSS governance and developer tooling.
