XRM
Requirements document to working app in a weekend.

XRM is a metadata-driven platform built with Blazor and EF Core. You define entities, fields, and relationships through a schema designer, and the platform generates the UI: grids, detail forms, child record views, all from metadata. Think of it as a lightweight any relationship management system.
The development process was the real experiment: I started with a requirements document on Sunday, and by Monday evening I had a working MVP with field and relationship designers, CRUD operations, child records, sorting, demo data inspired by AdventureWorksLT, and 71 passing tests. All through GitHub Copilot CLI.
