I will turn your excel spreadsheet process into a custom web app
Maximilian B.
About this gig
Your business runs on a spreadsheet that has outgrown itself: five people editing one file, versions by email, formulas nobody dares to touch.
I turn that spreadsheet into a real web app your team can rely on.
What you get
- A clean web app with logins and roles, built around your actual process
- Your existing data imported, nothing retyped
- Search, filters, validation and the exports you still need (Excel, PDF)
- Tested code, automated deployments and documentation
- Everything in your own accounts: no lock-in
How I work
- You send the spreadsheet and describe the process. I reply with a written assessment, including when an app is not worth it.
- Fixed scope and price before I start.
- Weekly preview links, so you see progress, not promises.
Reference: for an event agency in Germany I replaced their Excel inventory with a rental catalogue and a dispatch planner, synced to one shared back end.
Stack: Next.js, TypeScript, PostgreSQL or Directus.
Deutsch? Gerne. Ich arbeite auf Deutsch oder Englisch, Rechnung als deutsches Unternehmen, Hosting in der EU.
Please message me before ordering so we can agree the scope.

I'm Max, founder of Navigaite, a one-person software studio in Mainz, Germany. I build the tools a business runs on: web apps, internal dashboards and automations that replace spreadsheets, copy-paste and manual hand-offs. One engineer from first sketch to deployment, with tests and CI/CD. Code, hosting and docs live in your accounts, so the software keeps running without me. An event agency runs its rental catalogue and dispatch planning on my work. I reply the same working day, in English or German.

FAQ
Do you work in German?
Yes. Ich arbeite auf Deutsch und Englisch. Calls, documentation and invoices in either language.
Who owns the code?
You do. Code, hosting and documentation live in your own accounts from day one. No lock-in.
Is my data handled GDPR-compliant?
I'm a German business, use EU hosting where possible and sign a data processing agreement (AVV) on request.
What happens after delivery?
You get documentation and a handover session. Ongoing support and hosting are available as a monthly custom offer.
Can I order without talking first?
Please message me first. A two-minute brief saves us both a wrong scope, and I can send a custom offer that fits exactly.
