Hi, I'm Gabriel, an AI engineer. At my day job I lead development on an AI recruiting platform, so I spend a lot of time with Postgres, vector search and LLMs, and that's where I kept running into schemas we had to change after the fact. Before that I built a gamified training platform as a freelancer, and since I really like learning things in a game-like way, I put both together in SchemaWright, a place to practise database schema design against hidden tests on a real Postgres.
