Production apps that replace spreadsheet processes
A process living in a workbook and an inbox becomes a secure production application in two to six weeks. Fixed scope, EU hosting, and the source is yours.
What this is
Spreadsheets are where processes go to survive, and then to strain: one file, one owner, no history, no access control. This offering replaces one such process at a time with a small production application built against your real data. Scope is fixed before work starts, hosting is EU-resident, running costs for most internal tools are a few dollars a month, and the result is owned by your organization, source included. Where the idea is a product rather than an internal tool, the same discipline takes it to a shippable first version.
Who it fits
- A pipeline, register or schedule managed in a workbook that only one person can safely edit.
- Approvals, orders or requests that travel by email and get lost there.
- A process everyone works around because changing the spreadsheet feels riskier than living with it.
- A product idea that needs a working first version, not another specification.
What a typical engagement contains
- A scoping pass over the process as it actually runs, with the person who operates it.
- A first working version against your real data early, then short build cycles with that person in the room.
- Deployment to EU-resident hosting, with access control, backups and a known monthly cost.
- Handover: source code, documentation and a running system your team operates and owns.
Evidence
Sales pipeline app (own practice): Our own 15-year weekly-spreadsheet sales practice, replaced with a secure, EU-hosted pipeline app that runs for a few dollars a month, in production use within days.
Handwriting AI tutor: A bilingual AI writing tutor that photographs a student's handwritten work, marks it up like a teacher and adapts the next exercise, built and put into daily use in about six weeks.
Stampit Smart Card Suite for macOS: A shipped public macOS product that makes Bulgarian smart-card e-signatures work reliably in browsers and PDF signing. When a problem runs deeper than a web app, the work goes there too.
Multiplayer drawing game (alpha): A working alpha where friends take timed turns on a shared canvas while spectators react live. Real-time, multi-user software is in range when the process calls for it.
Bring the spreadsheet
Thirty minutes with the workbook is enough to scope the application that replaces it and to name a delivery window.
