Rapid prototyping for business apps.

The quoting tool, the customer portal, the dashboard, the booking flow, the CRM your business actually needs. A clickable, data-backed prototype first; then we keep going until it's the real thing.

01What a prototype means here

Not a slide deck and not a mockup: a working thing, built against your real data sources, that you can click through in days. The Instant Lawn Estimate for Montgomery Landscape started as exactly that — type an address, get a parcel, a measured lawn and a price — and was in production use within weeks, iterated to its twenty-seventh version.

02What it grows into

Prototyping is step one, not the product. The same codebase becomes the full website or custom app: accounts and sign-in, an admin console, email, and Stripe when the tool should bring money in. Three of the products in the showcase — Hall's Harvest Apiary, Prep for CISA and Coursing Club — have Stripe checkout, subscriptions or licences built in.

03Real integrations

Maps and parcel records, payments, email, Google Sheets, booking systems like Square, weather and sports data feeds. Coursing Club alone runs a scraper, a de-duplication pipeline, authentication, charts and a premium tier over 73,000 dogs' worth of data.

04Before anyone outside touches it

Every release is versioned and hash-verified, comes with a UAT checklist, and gets a security review before external users are let in. Coursing Club went through a six-dimension adversarial audit that surfaced 63 confirmed issues — all criticals and highs fixed before launch.

What you get

  • A clickable, data-backed prototype first; the production tool grows from it
  • Payments built in when the tool should earn — Stripe checkout, subscriptions, licences
  • Real integrations: maps and parcel data, email, spreadsheets, booking systems
  • Versioned, hash-verified releases, a UAT checklist, and a security review before outside users are let in

Questions

Straight answers.

What if the idea turns out not to work?
That's what the prototype is for: you find out in days, with a real thing in your hands, instead of after a long build. The blueprint and quote are scoped so the prototype is a complete, useful stopping point on its own.
Who owns the code?
You do. Every project ships as a repository or zip in your name, deployed to hosting and accounts you control.
Can it take payments?
Yes. Stripe checkout, subscriptions and one-time licences are all things I've shipped; Square booking too, where a business already runs on it.
