I build custom AI automations for your business.
I take one repeated, expensive manual workflow off your team's plate and build it into a durable AI automation: connected to your real tools, running in days not months, with a human approval gate so nothing fires without your sign-off.

Your team is doing the same manual work every week
Client reporting pulled by hand from three tools. The same support tickets answered over and over. Paid leads going cold because nobody followed up in time. Data re-keyed between systems. It is repetitive, it scales up exactly when you are winning, and it never ends.
Cut weekly reporting from hours to minutes
Pull the numbers from your tools, draft the report, and wait for one click to send. What took a half-day takes minutes.
Stop paid leads from going cold
A new lead gets a personalized reply and a booking link within about a minute, and you get alerted, so the leads you paid for stop slipping away.
A human approves before anything goes out
Every customer-facing step pauses for your one-click sign-off. The automation does the work; you keep control of what actually fires.
Built to survive the real world
If a step fails mid-run, the workflow resumes exactly where it stopped, and the approval gate means nothing reaches a customer without your sign-off. This is not a fragile no-code zap.
How it works
Simple, fixed-scope, and fast. No discovery-call runaround, no open-ended hourly bills.
Free audit call
We find the one workflow worth automating first and put a real number on the hours and dollars it is costing you.
Fixed-price scope, 50% to start
You get a one-page scope with an exact price and timeline. No surprises. The deposit kicks off the build.
Live in days
Your automation runs on your real tools, with the approval gate, plus a walkthrough video and a one-page runbook.
The Sire Founding Pilot
One fixed-fee engagement, not a menu. I personally audit your business, build 1-2 automations that save real time or money, and get you running on Sire so they stay governed after I leave.
Sire Founding Pilot
5 business days, start to finish. 50% to start, balance when it is live and you have signed off.
- Before day 1: a short intake so I show up already knowing your business, not guessing
- Days 1-2: diagnosis of what your team actually does, not what the org chart says
- Days 3-5: 1-2 working automations, built and tested against your real workflow, not a demo
- Onboarding onto Sire: approval gates, receipts, and a dashboard so you see and control what fires
- Ends with you running on a Sire subscription; your pilot fee credits toward your first month(s)
I'm only running 3 to 5 of these at once, an actual constraint on my calendar, not a scarcity trick. Founding customers lock their subscription rate at the founding price for as long as they stay a customer, even as list price rises later.
The engineering behind your automation
You would be one of my first automation clients, so here is the proof the code is real. I build the AI agent infrastructure most people only talk about — some of it open source, some of it shipping to real users.
Sire ↗
The engine I build your automation on: AI agents that run as durable workflows, survive crashes, pause for human approval, and connect to your tools.
Zerfoo ↗
A from-scratch ML inference engine in pure Go that runs 40+ model architectures and decodes ~28% faster than Ollama on Gemma 3 1B. Proof I understand AI at the metal.
Mint ↗
How I connect automations to your existing tools: turns an API spec into a working integration in seconds. The bridge between AI agents and your real systems.
Gist ↗
The retrieval engine that keeps automations accurate and cheap: 98.9% context reduction on a 754 KB spec, gated by a real CI test that asserts at least 80%.
Kazi ↗
The same discipline behind the approval gate, packaged for coding agents: declare a goal as machine-checkable predicates, and kazi loops Claude Code until every check passes — or stops to tell you why it's stuck, instead of quietly calling it done.
Valyrium ↗
A zero-dependency OpenAI-compatible HTTP gateway that routes Chat Completions requests straight to the Claude Code CLI, so any tool built for OpenAI's API can run on Claude models without a rewrite.
Blink ↗
An AI planning coach for iOS: talk to it like a person and it turns what you say into a real task with a real time on your calendar, then follows up with adaptive reminders until it's actually done.
Honest answers
Do you have clients yet?
I have built software for clients for over 20 years, including running my own dev consultancy for the better part of a decade and 8 years at Zendesk. You would be among my first clients for AI automation specifically, which is why founding-pilot pricing is below market and the work is backed by the scope guarantee. You get a seasoned engineer at a founder rate; I get my first automation case studies. The engineering behind it is real and public too.
Is the deposit refundable?
The deposit is non-refundable once the build starts, with one commitment: if the delivered automation does not do what the written scope says, I keep working at no extra charge until it does. If I still cannot make it match the scope within 7 days of your sign-off date, I refund the deposit in full. The balance is due once it is running and you have approved it; if I have not heard objections within 5 business days of handoff, the work is deemed approved.
Why not just use ChatGPT or Zapier?
ChatGPT is great for one-off answers; it will not watch your inbox at 2am or look up an order in your store. Zapier is fine until a run fails halfway and leaves things half-done, or you need an integration it does not have. I build crash-recoverable workflows that resume where they stopped, with a human approval gate, wired to the tools you actually use.
How fast can it be live?
5 business days, start to finish. Intake happens before day 1, days 1-2 are diagnosis, and days 3-5 are build, test, and handoff onto Sire. Fixed scope keeps it fast.
