Bintang Timurlangit

Hi 👋 I'm a full-stack developer and AI automation specialist based in South Tangerang, Indonesia. I build the thing, connect it to a model, and then make it run without me.

I work with small businesses and teams, owning the project end to end: shaping the system, building it, shipping it, then keeping it alive.

During my freetime, I write and maintain open-source MCP servers & tools.
