PORTFOLIO · 2026
PHATTHARAPHUMKINGCHAI
Full-stack Developer · Computer Science, Thammasat University
I build software people actually usefrom a registration system used by students from over 50 universities to systems for the National Radio Telescope.
I’m a software developer who loves stargazing. Right now I’m building AstroTrack3D for NARIT, and I just delivered the registration platform for RoV University Cup 2026 to Garena Thailand.

Worked with
01 — Selected work
Real systems, real users
The case studies I’m proudest of, picked from recent client work. Read on for the brief, the approach and the numbers that were measured.
02 — How I work
From a brief to a system a team can maintain
I don’t stop at “it works”. I make systems measurable, maintainable and ready to hand over with documentation.
02
Ship & operate
DevOps and observability
Docker, CI/CD, metrics and alerting with runbooks and docs, so the team can run it without me.

- GitLab CI
- AWS
- Prometheus

Make sense of data
Data, science and AI
Analysing radio-astronomy data, tuning LLMs and detecting objects — always showing where a number comes from, never guessing.

03 — Beyond code
Watching the sky with patience, building systems with dedication
I photograph the Moon, Saturn and Jupiter through my own telescope. I can stay deeply focused for hours on end — when stargazing, I can watch the sky all night. I bring that same habit to software: whatever I commit to, I pay close attention to detail and always give it my all.
- 01
Observe
Understand the problem and the user first
- 02
Measure
Tests, metrics and provenance for every number
- 03
Ship
Systems that run for real, with documentation
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.
