Custom App Development

You already built it. In spreadsheets.

I replace it with software you own outright.

Three steps. No surprises.

Weekly demos. Nothing disappears for a month.

Hand over

Your repository, your accounts, documented.

Worth building when this is true.

Build it

  • A spreadsheet has become the system of record
  • Off-the-shelf software has run out of room
  • Enterprise licensing cannot be justified
  • Something works, and only one person understands it

Not yet

  • A standard tool would do, properly configured
  • The idea has not been tested with anyone

I will say so on the call rather than after the invoice.

Built with

  • Next.js
  • React
  • TypeScript
  • React Native
  • .NET
  • Laravel
  • PostgreSQL
  • Supabase
  • Tailwind
  • Vercel

Questions I get before we start.

When a spreadsheet has quietly become the system of record. If the real state of the business lives outside the tool you pay for, and people believe the spreadsheet when the two disagree, the tool has stopped modelling how the business works. Until that point, configuring an existing product properly is cheaper and faster.

What you walk away with

One instrument. You own it.

Nothing held hostage, nothing locked to a platform you cannot leave.

The codebase

Yours, in your repository

The infrastructure

Your accounts, your billing

The accounts

Registrar, analytics, ads

The documentation
