EVAN acci /02
I'm Evan Oberfelder. I write systems in Python, Rust, and TypeScript that have to be fast, small, and correct.
On the side I hack on encrypted P2P file transfer, voice automation, and trading systems. The day job is running the9ines, a small agency in Austin.

Building software is the only thing I find consistently interesting. The systems I keep coming back to share three traits: they have to be fast, they have to be small, and they have to keep their promises under load.
Most of my work lives at the intersection of crypto infrastructure, voice and AI tooling, and the web. Rust and Python in the engine room. TypeScript on the surface. Postgres for state. Docker to ship.
Day to day I run the9ines, a small agency doing web, e commerce, and SEO for clients across cleaning, real estate, moving, and tax. Nights and weekends I ship Bolt, hyperclaude, TinyIntent, and a market making bot that lives on a Hetzner box.
