About this Gig

Stop letting users break your spreadsheets.


I build secure Google Sheets web apps using Google Apps Script to create structured, validated, and protected data entry systems.


Instead of giving users direct access to your sheet, I create a controlled web interface that connects to a protected database.


Perfect for:


  • Sales tracking
  • CRM systems
  • Inventory logs
  • Internal reporting
  • Team-based data collection


What you get:


  • Custom web form interface
  • Controlled inputs (dropdowns & validation)
  • Protected backend sheet
  • Automatic timestamps


Clean architecture for scalability


Send me your workflow and required fields before ordering so I can confirm feasibility.


Choose the right package for you:

  • Up to 10 fields
