Benefit

Turn a problem into a small tool that works, that you understand and that you can maintain, even if you have never coded.

By the end, you will be able to

  • write a simple specification: the problem, the users, the journey, the minimum version;
  • have a local tool built, and understand what each of its parts is for;
  • test and fix with AI;
  • keep versions with Git, without ever publishing a secret or personal data;
  • decide whether, and how, to go online, knowing the costs and the risks.

Demonstration

A small local web page built, tested and versioned, with a mistake fixed live.

Exercise and result

A local tool that is versioned, tested and documented. Going online is optional.

Hosting, database, login and payment: well-known services are presented as examples to compare, never as obligations and never as free without conditions.
