I will turn your excel spreadsheet into a custom web app


About this gig
Your business runs on a spreadsheet only you fully understand.
It works until someone else needs it, until it will not open on a phone, until there are five versions of the file in your inbox.
I turn that spreadsheet into a real web app. Same logic, same numbers but it opens in a browser, works on a phone, and nobody breaks a formula by typing in the wrong cell.
WHAT I BUILD
- Planning and forecasting tools: demand, stock, purchasing
- Operational dashboards your team opens every morning
- Calculators, quoting tools, internal admin panels
Forecasting is my specialty. My last project works out how much food a hotel kitchen must order, from occupancy alone no receipts, no barcode scanning, no new work for the staff.
HOW IT WORKS
1. You send the spreadsheet and say what decision it supports
2. I map your logic and confirm it back before writing any code
3. You get a working app - hosted, or as one file you own outright
No subscription. No lock-in. The source code is yours.
Send me your spreadsheet before you order and I will tell you honestly whether it is worth building.

FAQ
My spreadsheet is a mess. Is that a problem?
No. Most are. Untangling the logic is part of the job — I map it and show you the map before writing code, so you can correct me where I read it wrong.
Do I have to send you real business data?
No. Sample or scrambled numbers are enough to build against. If you do send real data, I sign an NDA first and delete it on request.
Who owns the code?
You do, on delivery. No subscription, no licence, no server you have to rent from me. If you stop working with me, everything keeps running.
Will it work without internet?
It can. I can deliver the app as a single file that opens straight from your phone or laptop with no connection at all — useful on sites with bad wifi.
Can it connect to the software I already use?
Often yes, if that software can export a file or has an API. Tell me what you use before ordering and I will confirm honestly whether it is possible.
I am not sure exactly what I want. Can you still help?
Yes, and that is the normal case. Describe the decision you make every week and the numbers you look at to make it. That is enough to start.
