Ground Up AI

Your clients stop texting “where are we at?”

I build client portals, referral tracking and workflow automation for businesses in Fairfield County and Westchester. Fixed price, live in weeks, and the code is yours.

Three things I build, at fixed prices

Every build is scoped up front, runs in your own accounts, and comes with a care plan so it keeps working after launch.

Client Portal

$9,500
Live in 4 weeks

For builders, remodelers, trades and firms whose clients want constant updates.

  • Branded client login
  • Progress, photos and documents
  • Selections and change orders approved online
  • Text and email notifications
  • Admin tools for your team

Care plan from launch: $750/month

Referral & Partner Engine

$12,500
Live in 5 weeks

For agencies, advisors and brokers who grow through referrals and can’t see who sends them.

  • Personal referral links by text and email
  • Partner portal with status and rewards
  • Admin view of every referral, start to close
  • Partner terms accepted and recorded
  • Monthly owner report

Care plan from launch: $1,000/month

Automation Sprint

$4,500
Done in 2 weeks

For one workflow that eats hours every week, fixed in ten business days.

  • Connects up to 3 tools you already use

Care plan from launch: $500/month

Not sure what you need? Start with a $750 Blueprint: a 90-minute working session, a mockup of the key screens and a fixed quote. The full $750 is credited if you build within 14 days.

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.

Client portal

A luxury home builder in Fairfield County

Homeowners were getting updates, selections and change orders across texts and email threads. Now it’s one branded portal.

  • Project progress, photos and documents
  • Selections and change orders approved online, time-stamped
  • Team posts updates in minutes

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.

Tell me what’s eating your week

Twenty minutes, no pitch deck. If custom software isn’t the right fix, I’ll tell you what is.
