Backend engineer working on Go infrastructure, cloud-native tooling, and reliable data paths. I reproduce a defect locally, write the failing test first, and open a PR only after the affected suites, vet, and formatting are green. Most fixes start with a failure I actually hit: a writer that accepts only part of a buffer, a reader that mistakes a write error for a clean end of stream, an inherited environment scope that quietly widens.
Merged pull requests only. Still-open and withdrawn PRs are deliberately omitted - I would rather show the fixes that actually shipped.

🛠️ klauspost/compress - #1302:
gzip.Reader.WriteTostored a destination write error inz.err, which doubles as the end-of-stream marker. A failed write was therefore mistaken for a clean end of stream and the CRC/trailer check was silently skipped. Writer errors are now wrapped with%wso they stay distinct fromio.EOF. Merged by the author. -
⚡ k8sgpt-ai/k8sgpt - #1845: Findings already known to an operator had no way to be silenced, so every analysis re-reported them. Added an
exclusionsconfig key with a content hash and expiry, applied before analysis and in server mode, with the muted count reported so a mute cannot silently swallow findings. -

🗄️ cybozu-go/moco - #966: The Helm chart gave controller pods no way to carry custom metadata. Added support for custom labels and annotations on controller pods.

Bug reports, reproducible failures, and patches for upstream Go projects are always welcome. The fastest way to reach me is email; the profile above stays the source of truth for my work.
