Good software needs people

AI can write code. Shipping a product people love still takes judgment, care and ownership.
That’s what I bring to every project.

Psst, open a note for the full story.

I don’t just write code.
I ship software that runs.

The whole stack, built end to end.

I design the schema, write the API, build the UI and ship it in containers. One person owns every layer, so nothing gets lost between them.

See what I’ve built

Tested in production,
on apps people use.

At Tri Petch I worked on the my-ISUZU backend: NestJS and GraphQL APIs, monitoring with Datadog, and fixing live issues under tight deadlines.

Faster teams,
not just faster code.

On Sigma Learn I containerised the backend and automated local setup, cutting onboarding from hours to minutes, and standardised API responses so frontend and backend speak the same language.

One developer. The whole stack.
