About this gig

Tired of paying monthly for software your shop barely uses? I build simple, mobile-friendly web apps that run inside your OWN Google account - with no monthly server cost.


What I can build for you:

  • Daily sales / report input from staff phones
  • - Inventory, booking, or shift management
  • - A live dashboard of your Google Sheets data
  • - Internal forms that save straight to a spreadsheet

Why me: 10+ years of real on-site operations experience. I understand how a shop actually runs, so I build tools people will actually use - not overcomplicated software.


How it works: I write the app, you just open a link on any phone or PC. Nothing to install, and you keep full ownership inside your own Google account.


Message me with the task you want to simplify (a screenshot of your sheet helps) and I will tell you exactly how a small web app can solve it.
