Nattawut K.

I build web apps, APIs and the servers behind them.

A developer who works across the whole stack, from the web page to the server, and likes building small software that fixes everyday annoyances.

02 / About

From web page to server

Full-stack developer.

So far I have mostly built web apps, for clients and as small software of my own, from the pages people see to the APIs and servers behind them.

I can build for the web, mobile and Mac, write APIs, and look after servers and deploys. The web is still where I am most at home.

AI is part of my everyday work now. It helps me draft code, review changes and write tests, while the decisions and the final check stay with me.

Next, I want to keep making small tools that fix everyday annoyances, like Cmdly, and keep finding better ways to use AI in my work.
