An electronics store with a shared order database: storefront, phone-number sign-in, staff roles. The server is plain Python with zero dependencies.
An electronics and accessories store: a catalogue with categories, a cart, checkout, phone-number sign-in, and different permissions for customers and staff.
The interesting part is the server. The first version lived entirely inside one HTML file and kept everything in browser memory — an order placed on a phone was invisible on a desktop, which for a shop is meaningless. The server fixes exactly that: there is now a shared database, and the owner sees a customer's order from any machine.
It is written against the Python standard library alone: http.server for routing, a JSON file in place of a database, bearer tokens in the Authorization header. Not a single third-party dependency, so it runs anywhere Python exists, with nothing to install.
That is a deliberate trade-off and the code says so out loud. Before this could take real money, four things are marked in the source as required replacements: real SMS instead of returning the code in the response, a payment gateway instead of the current stub, PostgreSQL instead of the JSON file, and password hashing with HTTPS. Writing that down was the point — a demo that pretends to be production is worse than a demo that admits it.
