Backend Engineer | Cloud Native | Data Infra — I fix correctness defects that only surface in real environments, with a failing regression test before every patch.
Go · Python · K8s · Docker · Prometheus
Merged upstream pull requests, each with the defect it removed:
- juanfont/headscale#3650 — Reject pre-0.23 databases that lack a migrations table instead of migrating them blindly.
- pranshuparmar/witr#242 — Replaced a symlinked root
main.gothat Git for Windows checks out as a 16-byte text file, sogo buildfailed on a real clone while CI stayed green; added a lint guard. - dagucloud/dagu#3554 — Honour
mark_successfor non-retryable exit codes. - dagucloud/dagu#3578 — Regenerate
llms.txtand add a CI check that keeps it in sync with the skills tree. - k8sgpt-ai/k8sgpt-operator#855 — Add tolerations to the K8sGPT CRD and chart so the controller can run on tainted nodes.
- bmf-san/ggc#542 — Make the config and command tests pass on Windows.
I strictly follow TDD and ensure all CI checks pass before submitting a PR. No spam, no low-value commits.
