My tmux Test SIGKILLed the Agent Running It
I tested a tmux message tool inside the live session that held my coding agent. One missing target killed the agent's own pane. The fix was a disposable tmux socket.
● Urgent-care operator · AI-agent engineer
I build AI that makes urgent care faster, better, and less exhausting to run.
A growing share of my urgent-care company's operations runs on a fleet of AI agents I built — and I write down how it actually works so you can use it too.

See how AI actually runs the operations
Intake, scheduling, charting, billing — the whole day, run by agents, with a human on the calls that matter.
How I run it → You build with AITake the patterns I use every day
Agent harness, self-verification, recovery, the failures nobody screenshots — written to lift straight into your own agents.

Tutti
A bilingual classical-music learning product that guides people through pieces with stories, context, and things to listen for — not intimidating analysis or assumed expertise.
Patient Portal
A single web platform that runs a clinic's whole day — check-in, a live provider queue, lightweight charting, telehealth, staff messaging, and billing — instead of a dozen disconnected legacy tools.
Firstmate
The sole captain-facing product surface for dispatching agent work: Firstmate routes goals through persistent secondmates, keeps subordinate workers internal, and watches sessions for trouble — rate limits, context exhaustion, dead sessions — so work can recover automatically.
If this is your kind of problem, email me.
Building agent systems inside a real business — or running a clinic and wondering what this could look like for you? That's exactly the conversation I want to have. No form, no funnel.
