I like backend work that gets close to real infrastructure: Kubernetes resources, auth boundaries, storage, networking, CI, and the quiet glue that turns a feature into something maintainers can actually merge.
- Platform backends: APIs that manage real cluster resources, not just rows in a database.
- Kubernetes edges: Services, Ingress, cert-manager, RBAC, StatefulSets, storage, pod logs, and exec paths.
- Open-source maintenance: small fixes with a reproduction, a reason, and tests when behavior can regress.
- Agent infrastructure: memory, retrieval, tool calls, and the backend paths agents need when they leave the demo.
- I read the surrounding code before touching the line that looks guilty.
- I prefer boring patches in the best sense: narrow, explainable, and easy to review.
- I enjoy the part where a vague bug becomes a concrete failing path.
- I tend to build bigger ideas in a fork first, then upstream the pieces that have earned their shape.
- I care about the last 20%: names, error paths, tests, and whether the next maintainer can follow the trail.
The number I watch on GitHub is not stars. It is the patches a maintainer read, trusted, and merged — 23 so far, across 6 upstream repositories.

A Kubernetes-flavored local cloud OS, and my main upstream: App Store installs, worker nodes, certificates, RBAC, Services, storage, and the CI that guards them.

I keep this profile less like a CV and more like a workbench. The interesting part is not a label; it is the trail of small decisions that make a system less mysterious than it was yesterday.
