AI automation for small teams
Support replies, lead follow-up, admin, reporting — the manual tasks that quietly eat your week. I design and ship working automations in weeks, not months, on a fixed scope and price.
What I can build for you
Concrete, productized builds — pick the outcome you need. Each is scoped to your tools and shipped end-to-end.

How we work
01
We map the workflow that's costing you time or money, the tools you already use, and what a win looks like in the next few weeks.
02
I build a working prototype or audit on a fixed scope and timeline — no open-ended retainers, no surprise invoices.
03
You get a usable system, the integration plan, and the metrics to prove it's working. We decide together what to build next.
Pricing
Mid-market pricing for senior, end-to-end delivery — I compete on outcomes, not on being the cheapest. Your exact scope and price are agreed on the call.
