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:

  1. You show me your current sheet or process
  2. I write down the rules and confirm them with you
  3. I build with AI-assisted development and review every rule myself
  4. 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.

I spent 12+ years doing billing, tracking and reporting by hand at a national seaport. Now I build the systems that replace that work. If your team runs on spreadsheets, paper forms or hand calculations, I'll turn it into a web app that calculates, tracks and reports on its own. Three of my systems are used daily: a port billing calculator, a vehicle tracking app and an overtime billing system. I start by learning your workflow and writing the rules down. Then I build with AI-assisted development and test against your real numbers before handover.
