Turning curiosity into code

I build things to understand how things work.

I'm a9lim, a Singaporean developer with an unreasonable number of interests. Physics, biology, finance, political science, religion, AI, music — if it has structure worth exploring, I've probably tried to simulate it.

Most of what you see here is vibe-coded with Claude — I steer the direction, Claude writes the bulk of the code, and we iterate until it works. The result is a collection of open-source, zero-dependency browser tools that run anywhere without frameworks or build steps.

Beyond simulations, I build AI agents, discord bots, sacred text readers, and whatever else catches my attention. I care more about shipping things that are useful than about doing things the "proper" way.
