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.
