How a build runs

You see working screens in the first week, not a slide deck.

  1. Kickoff and build

    We confirm scope and I set everything up inside accounts you own. Working screens on a private link by Friday.

  2. Your review

    A 45-minute session where you click through it and tell me what’s wrong.

  3. Real data

    Revisions in, your projects and contacts loaded, your team invited.

  4. Launch and training

    Go live with a recorded training and a handoff document. Care plan starts.

Two build slots open this fall

I take a small number of builds at a time so each one launches on schedule. Book a 20-minute intro to see if yours is a fit.

Book a 20-min intro

You own it. I keep it running.

Most software locks you into seat fees. Custom software from me is built in your own accounts from day one.

Your code, your accounts
The code lives in your GitHub. Hosting, texting and email run on your accounts, billed to you at cost, typically $20–60 a month.
A fixed price
Scope is written down before we start. Changes are quoted in writing before any work happens.
Built fast, without cutting corners
I use AI-assisted development to deliver in weeks, with tests, documentation and a full handoff.
A care plan after launch
Monitoring, security updates, backups and small changes every month, so it doesn’t break the day after I leave.

Free: see how you show up on Google

Two things you can have at no charge, whether or not we work together.

Free with every intro call

See where you show up, and where your competitors do

On the call I’ll check your site live: Google search, your Business Profile, and whether AI search tools recommend you or someone else. You leave knowing exactly what’s missing.
