I'm a developer based in Thailand. I've been writing code and putting it on GitHub since 2016.

Like a lot of people, I started out with games. My early projects were Minecraft tools, like a UUID generator for premium and cracked players, and ChatPixelArt, which turns images into pixel art in the chat, made possible once Minecraft 1.16 added full hex colour support. After that I moved on to taking things apart to see how they work. I wrote a tool that gets video stream URLs from CCTV recorders, a Node.js client for the legacy Blynk IoT protocol that I reverse-engineered, and hydr, a CLI that downloads files faster by splitting them across parallel requests.

One of my most popular open source projects is promptparse, a JavaScript library for reading and generating PromptPay and EMVCo QR codes. It has over 200 stars on GitHub and gets more than 100,000 downloads a year on npm.

I run a few side projects of my own. FavorList, which started in 2020, is a media site about pop culture and new-generation lifestyle, with the motto "Dive into it". My other one, Makerneed, started in 2025 and is an online 3D printing service. You upload an STL or 3MF model, preview it in 3D, pick a print farm and a colour for each part, and get a price straight away. Then you pay with PromptPay and follow the order until it arrives.

Freelance work is part of the mix too. In 2025 I rebuilt the website of the Office of Academic Affairs and Registration at Rajamangala University of Technology Lanna (academic.rmutl.ac.th) with SvelteKit. It serves more than 15,000 students across six campuses, and I extended the university's registration system with a student portal and course section search.

At RDCW and AONA, I contribute to their products. I helped develop an early version of Slip Verify by RDCW, a slip verification service that lets online shops and developers check Thai bank transfer slips. For AONA's EasyDonate, a donation platform for Thai streamers and creators, I made Paper Plane, a soft, minimal, blue donation page theme that gives donors a clean first impression.

I like working across the whole stack, from servers and virtualization all the way to the screen people actually touch. You can find more of my freelance work and projects at wazt.net.
