Thesis

Balance Game System

A real-time feedback loop built in Unity (C#) and Arduino. Physical sensor input drives dynamic game response — iterative calibration, embedded logic, same systems thinking I bring to prompt design.

Looking For

Prompt Engineer roles — AI product teams, research, or tooling. Remote-friendly. Curious about problems where the gap between a vague idea and a reliable output needs bridging.

I told you not to open this.

01

This whole website is a project. You're literally inside my portfolio right now.

02

Interned as a sound engineer at The Standard. Turns out mixing audio and writing prompts need the same brain — precise inputs, clean outputs, zero noise.

03

Currently building an AI trading system. It's sometimes wrong. I'm working on that.

04

22. Bangkok-based, dreaming remote. Open to interesting problems anywhere in the world.
