programmer · systems / production / tooling

I build the systems behind the game.

I'm Yee Sen, a programmer focused on maintainable full-stack systems, production fixes, and the tooling that keeps software running.

01 / flagship build

The project I’m most proud of: release-phase ownership across the full programming stack, followed by ongoing production work.

What I Actually Work With.

Not a progress-bar wall. These are the areas I use to design, ship, debug, and maintain Roblox projects.

I like systems that survive release day.

Most of my work sits where gameplay, UI, state, staff workflows, and live maintenance meet. I care about code that stays understandable when a project grows, not just code that demos well once.

Creamá 1.5 is the best example: I owned programming through its development-to-release phase and still support the project while working on Version 2.
