I build AI agents and the systems they run on, the way [Factorio](<https://store.steampowered.com/app/427520/Factorio/>) taught me: design the factory, don't do the work. When the open-source agents I use fall short, I fix them upstream on [GitHub](<https://github.com/zerone0x>).

## Letter

Hey there,

Thanks for climbing all the way up here.

I'm Manlun. I've loved computers for as long as I can remember, and somewhere in the countless hours I spent in Factorio I learned the lesson that still shapes how I work: the real game is never doing the work yourself — it's designing the factory that does it for you.

These days that factory is made of AI agents. I'm a founding engineer building agent products, the runtimes they run on, and the developer tools around them — the unglamorous parts like sessions, sandboxes, routing and evaluation loops that decide whether an agent actually ships. When the open-source agents I rely on fall short, I fix them upstream.

Away from the keyboard I'm usually [watching something](<https://blog.trine.dev/posts/2026-05-17-toptv/>) — anything Larry David first — or [playing something](<https://blog.trine.dev/posts/2025-12-23-game/>), from puzzle games like Recursed to a long night of Factorio. And when I'm overthinking something, I write it down on [my blog](<https://blog.trine.dev/>).

If any of this resonates, write back — I read every letter.

Manlun
