# 🛠 Bespoke application development

 *Specialised in **application revamps** for SMEs and non-profits. 100% remote, human support.*

 I offer three main services: replacing an unmanageable Excel file with a web application, revamping a fragile AI/No-Code prototype, or modernising a legacy system (PHP, Access, FileMaker). Every project starts with an audit to scope the need before quoting a price.

 ### 📊 Replace Excel with a web application

For SMEs and non-profits who have hit the limits of Excel: errors, slowness, no way to collaborate. Excel technically caps out at 1,048,576 rows per sheet (source: [Excel specifications, Microsoft Support](https://support.microsoft.com/en-us/office/excel-specifications-and-limits-1672b34d-7043-467e-8e27-269d656771c3)) - a ceiling some business uses hit sooner than expected, not counting the slowdowns that show up well before that limit.

**✅ What I do:**

- Analysis of your current Excel files
- Development of a **bespoke** web application
- Training for your team
- Maintenance and future improvements
 
**💰 Pricing:** Free audit | MVP from **€800** (2 weeks)

 ### 🛠 Prototype revamp (AI, No-Code)

Your AI/no-code application works... until it crashes. I rewrite it properly.

**✅ What I do:**

- Free audit of your prototype
- Revamp with a **clean architecture**
- Complete documentation
- Training so you can be autonomous
 
**💰 Pricing:** Free audit | Revamp from **€1,200**

 ### 🏛 Legacy system revamp

Is your system (PHP, Access, FileMaker...) from the 2000s? I modernise it without breaking everything.

**✅ What I do:**

- Technical audit (€200, refunded on signature)
- Progressive migration
- Training for your team
- Post-migration support
 
**💰 Pricing:** €200 audit | Migration from **€2,000**
