ABOUT

From experimenting to building software that actually works

A Computer Science student at Thammasat University who started with video editing and 3D, then fell for building things people actually use. Currently building a system for NARIT and open to freelance work.

01 — Story

Three key chapters

Chapter 1

Trying things out

I started by playing with editing and 3D tools — Sony Vegas, SketchUp, Maya and Blender — then moved on to Adobe’s Photoshop, Illustrator, Premiere Pro and After Effects. They kept me helping out with school projects and gave me my first taste of the joy of making things with a computer.

Code is what brings software to life.

Chapter 2

Finding my own way

I chose Computer Science and enjoyed solving logic problems in C, C++ and Java, but a command line felt hard to touch. So I turned to the web, starting with PHP and a reading-log app of my own that grew from a C version into PHP and finally Next.js.

I wanted to see people actually use what I build.

Chapter 3

Real systems, real users

From freelance jobs and coursework to the RoV University Cup 2026 registration system used by 51 universities, and AstroTrack3D, a web workspace for NARIT’s 40 m radio telescope. I like structuring the work, splitting tasks and writing the docs a team can carry on with.

Handed over so a team can run it — not just finished.

02 — Journey

Year by year

The turning points, from playing with software at school to systems with real users.

  1. School years

    The curious experimenter

    Editing, 3D and design work for school events, plus a handful of competitions: 1st runner-up in Computer Design (SketchUp), video editing, a science & math talent contest, and Northern representative in the national Thai Encyclopedia quiz. Graduated with a 4.00 GPAX in Science–Math.

  2. Thammasat begins

    Into Computer Science

    The foundations of the craft — C/C++/Java, data structures, algorithms, networks, operating systems, databases and software engineering — and the discovery that I like building tangible things on the web.

  3. 2023 – 2024

    Open House staff, CS programme

    General staff at the programme’s Open House — practice at coordinating on the ground with lots of people.

  4. 2024

    The first sites in real use

    My own expense and reading tracker (C → PHP → Next.js) and a freelance amulet-marketplace platform for Luangphor Khian, used by real customers.

  5. 2025

    Trying many different things

    A corporate site for Phrom Engineering, a realtime seminar seat-booking system, an automatic IoT watering system, an AI chatbot and object-detection coursework, and event artwork for BYENIOR 2025.

  6. 2026

    Bigger, more complex systems with many real users

    Delivered the RoV University Cup registration system (Mar–Sep) and, since June, building AstroTrack3D and NashGUI for NARIT.

03 — Principles

What I hold to — and the proof

Not slogans: each one is backed by work you can open.

Don’t guess — show the source

Every value in AstroTrack3D carries its source and time; if it can’t be computed it says “unknown” instead of inventing a nice-looking number.

Hand over something others can run

11 runbooks, 88 alert rules, and 9 documents plus a QA test guide for RoV Cup — so the team can operate it without me.

Design so users finish

An 8-step form with recoverable drafts and rules checked on the client, so applicants from dozens of institutions actually get through.

Care about the details

Even Thai vowels and tone marks on the team directory must render correctly, and documents should be tidy enough to hand to someone else.

How we’d work together

  1. 01

    Talk through the brief

    Goals, users and constraints.

  2. 02

    Design & prototype

    See the look and flow before real code.

  3. 03

    Build in short rounds

    Regular demos, adjusting to what we see.

  4. 04

    Hand over with docs

    Your team can run it without me.

Small-to-medium systems can be hosted on the stack I know best (Next.js, Prisma, MySQL) for under 1,500 THB a year.

Got a brief or an idea? Let’s talk

A company website, a registration system, a dashboard or a specialised tool — tell me about it. I’ll help work out what’s possible and make it run for real.
