30 days, 386 commits, non-dev: building a factory's production system with Claude Code. What am I missing?

A non-developer built a production management web app for a furniture plant in 30 days using Claude Code. The project, which started on September 4th, resulted in a tool now used daily by the office and shop floor. It features 386 commits, is currently v2.54, and comprises approximately 175k lines of Python and vanilla JS, 2,100 tests, 580 API routes, and 280 SQLite tables. The stack includes FastAPI, SQLite, and plain HTML/JS with Tailwind, running on a Windows machine, with all UI and code in French.

This account details a non-developer's first successful use of Claude Code to build a factory production system, unlike typical reports focusing on developer use cases.
