Commercial work first, then the deeper technical pieces.
The site uses only verified project details from the existing portfolio and resume. The goal is to show recruiter-friendly context without inventing anything.

Toolbox
A practical stack across gameplay, systems, and production support.
The pitch is simple: enough engineering depth to build systems, enough production awareness to ship them cleanly.

About
Technical, creative, and reasonably calm about it.
I’m an interactive media developer based in Singapore. My background spans commercial Unity/C# work, game systems, editor tooling, and earlier C++ / custom-engine experience.
I like building things that are useful to teams and understandable to players: UI systems, gameplay loops, live-ops support, tools that reduce friction, and the unglamorous pieces that keep production moving.
The short version: I can sit between creative intent and implementation detail without turning the codebase into a shrine to my own cleverness.
Let’s talk
The cleanest route to the portfolio is still a direct message.
Based in Singapore. Open to Unity, gameplay, and interactive media roles.
