Marketer turned agentic builder, shipping software at an unreasonable pace.
Growth Engineer at Lindy in San Francisco, running product-led growth experiments. Built agents with thousands of professionals through a community we grew, before becoming what I like to call an "agentic builder" — a fancy way of saying I built myself a system with agents to ship software at an unreasonable pace. This site is where I write about it as I go.

My AI coding agent spend is getting ridiculous: 2x Codex Max, Claude Code Max, Cursor Max, OpenRouter, DeepSeek API, Baseten, and Cerebras.

Discovered Rustrak and now use it on my VPS. Already connected a bunch of my pages.

Installed bottom on the VPS. Rust-written htop replacement, runs right in the terminal. CPU, RAM, network, per-process, all on one screen. Finally know what is eating memory when an agent goes feral at 2am.

Moved my coding agents off my laptop. They live on a Hetzner box now. Claude Code and Codex run inside tmux, reachable via mosh. I close the lid, walk to the café, reattach from my phone, they are still going. The work stopped being tied to where I am.

My coding-agent token usage
59.9B
tokens went through my coding agents in the last 30 days, across 7,096 sessions. This is who did the work.
58.2B of that is cache reads: context the agents re-read on every turn. 1.74B is new input, output and cache writes.
