Security & Privacy

  • Data sovereignty

    I never see your data. The script runs entirely within your Google environment.

  • Code ownership

    You own the source code. No hidden backdoors or obfuscated logic.

  • Zero-access policy

    Limited-scope permissions—I only see what is necessary to build the tool.

The Problem

Out-of-the-box SaaS tools are too expensive or don't fit your company's unique workflow. You need an employee portal, a custom inventory system, or a project-tracking dashboard, but you don't need another monthly subscription or a product that does 90% of what you want.

The Solution

I build custom-coded HTML/JavaScript interfaces that live inside Google Workspace and use Sheets as the database. No separate server, no hosting bill. Your team logs in with Google; the app runs in the browser; the data stays in your Workspace.

  • Forms and dashboards that read and write directly to your Sheets.
  • Workflows that trigger on submit, emails, approvals, status updates.
  • 100% ownership of the code. You can extend it or hand it to another developer later.

Use Cases

  • Employee portals: Request time off, submit expenses, view company data, all in one branded app.
  • Custom inventory management: Track stock, reorder points, and history in Sheets with a simple UI on top.
  • Project tracking dashboards: Status, assignees, and deadlines in one place, powered by Sheets and Apps Script.

Benefits

  • Zero hosting costs: Runs on Google's infrastructure.
  • Secure Google Login (SSO): No separate user management.
  • 100% ownership of the code: No lock-in. Full documentation included.

Without the SaaS price tag. Tell me what you need, a portal, a CRM, or a dashboard, and I'll scope it for Google Workspace.
