crescendo — Guitar-school Portal

Problem

Guitar teachers typically juggle calendar apps, paper schedules, WhatsApp and Excel — evolved over time, not chosen on purpose. Students often don’t know exactly what to practice, and teachers spend a lot of time on pure organization instead of actual teaching.

Solution (prototype state)

A lightweight Django portal with scheduling per student, task management (practice pieces, scales, chords), simple progress tracking, and a GDPR-friendly baseline — no tracking, no external analytics.

Running in production as a prototype on a small Hetzner server at kreativer-gitarrenunterricht.de/crescendo/, used by a handful of testers (teachers from my private network). No paying customers yet — that’s the next step.

What this project shows

• End-to-end execution: domain, deployment, database, auth, UI — from one person.
• Clear GDPR foundation from the start (DE hosting, no third-party services).
• Iterative work with real users, not just mockups.
• AI-augmented development: Claude Code as co-pilot lets me ship Django conventions + modern UI in parallel.

What this project does not claim

• No 900 active users, no million-euro revenue.
• Not “in production for years” — started 2025, prototype status.
• Not a finished product — active iteration, some features still MVP-level.
