About
I'm Puwanat, a software engineer in Bangkok. I build web products end to end — the data model, the API, the admin tooling and the public interface — mostly with TypeScript, Next.js, Node.js and PostgreSQL. I like the parts around the code just as much: deployment, backups, CI gates and the small operational details that keep a thing running after launch day.
Lately my own projects have drifted toward tooling for physical and financial systems: a simulation-first IoT platform where firmware runs on emulated boards before any hardware exists, a trading bot that has to prove itself in a sandbox before it is allowed anywhere near real money, and this site, which doubles as my playground for a bilingual CMS.
I care about software that is small, well-crafted and honest about its limits: fewer moving parts, verified before it ships, and documented so the next person — often future me — can pick it up without a walkthrough.

The system of record for a vacation-ownership business: the contracts members sign, the interest that accrues on them, the annual fees they owe forever after, and the nightly close that moves all of it forward one day.
