Available for backend work
Backend developer who ships practical APIs and keeps the details boring. Slow? Fixed. Fragile? Hardened. Not deployed yet? Built.
I work closest to backend systems, infrastructure, and the product edges where reliability actually shows up.
Most of my recent work has involved Claude Code, Codex, and harness engineering. I focus on tightening development automation and repeatable verification flows.

Always open to a practical build, a backend cleanup, or a production problem that needs a calm pair of hands.
