I will turn your excel workflow into a custom web app


About this gig
Is your team still running billing, tracking or approvals in Excel, on paper or by hand? I'll turn that workflow into a web app your team opens from a link.
Who I am: 12+ years in billing, cargo tracking and revenue reporting at a national seaport. I built three systems now used daily there: a billing calculator, a vehicle tracking app and an overtime billing system.
What you get:
- A web app built around your exact rules and calculations
- Works on desktop and mobile, prints clean A4 reports
- Saved records, Excel export and change history (depending on package)
- Tested against your real numbers before handover
- Low-cost hosting on Cloudflare, often inside the free tier
How I work:
- You show me your current sheet or process
- I write down the rules and confirm them with you
- I build with AI-assisted development and review every rule myself
- You test with real data, and I fix anything that doesn't match
Good fit: quote and invoice calculators, stock or vehicle trackers, overtime sheets, approval logs, internal dashboards.
Please message me before ordering so we can confirm scope.

FAQ
Do I need to know coding?
No. You explain how the work is done today, and I handle the build and the hosting setup.
Can you work on processes outside logistics?
Yes. I start by learning how your process runs and confirm every rule with you. I don't claim to know your industry already.
Will my data stay private?
Yes. Your data is kept in your own private storage, and I explain the setup before we start building.
