Harnix
Repos are messy, and AI agents waste whole sessions rediscovering that. Harnix checks what a codebase is missing and tells you what to fix first.
Software Engineer · AI Loops · QA
I stress-test agentic loops with evals and harness engineering. I built and led engineering for venture-backed products end to end. I've shipped high-availability DevOps and systems that run themselves.

Thai companies selling to the EU lose contracts to compliance stuff. We automated boring parts, and won the Thai Board of Investment endorsement.
Owned the whole thing technically, database to deployment. Grew it to ~2k people, ~300 of them paying vendors, and an investment round.
Language learners kept getting stuck with apps that need a connection. Ours works offline, and a few hundred people have learned thousands of words with it.
Kept 500+ schools online with auto-scaling and high availability. It was a one-person ops job.
Wrote deep-dive engineering articles and books that developers still come back to.

tangochangmai ↗I recorded an album, because the other half of my brain needed a turn.
luzdealba.bandcamp.com ↗I studied biology before software, which is probably why I think in systems.
A short film followed the tango community in Chiang Mai.
