About

Engineering work with room for play.

I am a game developer and software engineer based in Indonesia. I work across game development, developer tooling, and practical AI-agent pipelines.

Current focus

My current work combines game systems with the engineering practices that make complex work repeatable. I am interested in tools that help developers move from a useful idea to a verifiable implementation without hiding the important decisions.

Game development background

Games are where I keep returning to questions about feedback, systems, and player understanding. Idle Boss Slayer is a web-first idle prototype built around a deterministic simulation, readable progression, and layouts that work on both desktop and phone screens. I use small prototypes to learn early, before asking an idea to carry unnecessary production weight.

Developer experience and tooling

I build developer tooling and AI-agent pipelines through Hephaestus, a framework that records the gates used to make a change. The point is not automation for its own sake: a result should have enough evidence behind it that the next person can inspect, reproduce, and improve it.

Current experiments

Toybox is a place for web-first game experiments, from readable interactions to playful systems.
