About

01 — The pivot

The pivot

For four and a half years I served as a police officer at Phahonyothin Police Station. On night shifts and days off, I taught myself to code.

It started as curiosity and became the thing I kept choosing. While still in uniform, I built and shipped software real people use: a trip-tracking platform with a public Android APK, a multiplayer game running live on a server I manage myself, and the automated tests behind both.

In June 2026 I resigned to become a software engineer full-time.

This wasn't a whim. Nobody leaves a stable government career for a maybe. I left because after years of building before work, after work, and on days off, the evidence was clear: this is what I do, and I'm ready to do it as my job.

02 — How I work

How I work

Career-changers don’t get the benefit of the doubt, so I built my habits around proof.

1. 01 / 04

   I own the full lifecycle.

   Design, code, tests, CI/CD, deploy, and production on a self-managed VPS. On AiKlao and Typing Race I was the mobile developer, the backend developer, and the ops person — there was no one else to hand off to.

2. 02 / 04

   Tests gate my releases.

   500+ automated tests across six repositories (Jest, JUnit, Supertest, Playwright, GUT). On my projects, a CI gate blocks the release build on any red test — not as policy theater, but because I’ve seen what slips through without it.

3. 03 / 04

   I think in edge cases.

   What happens when two SOS requests arrive at the same instant? When a player pastes the whole passage instead of typing it? Finding the failure mode before the user does is the job.

4. 04 / 04

   I use AI as a tool — and own every decision.

   For Tiger Kick I designed a review-gated development process: role-scoped agents, mandatory code review, QA exit gates. The AI executed; the architecture, the quality bar, and every accepted line were mine.

03 — The path

The path

1. 2022

   Royal Thai Police

   Police officer at Phahonyothin Police Station. Shift work, real stakes, no room for sloppiness — and, off-shift, teaching myself to code.

2. 2024

   42 Bangkok

   Project-based, peer-reviewed computer science school. No lectures — you build, and your peers review your code. Learned to defend my work line by line.

3. 2025

   First shipped app — AiKlao

   Real-time group trip-tracking platform: LINE bot, LIFF web, and a React Native app on one shared backend. Public Android APK, running in production on a self-managed VPS.

4. 2026

   B.Sc. Computer Science — and all in

   Finishing a B.Sc. in Computer Science and, in June 2026, resigned from the police to pursue software engineering full-time.
