The story

Algerian building codes exist. But finding the clause that covers your slab means knowing which document to open, in a corpus written across two languages, and then reading it in a third if that is the one you think in.

So people ask a colleague instead, and the answer is whatever that person remembers. For seismic rules and rebar spacing, “whatever someone remembers” is holding up the building.

The product

The console is the part I’d build first if I started again, because the real improvement loop is someone reading a bad answer and wanting to change one line, and that loop dies if it needs a release.

Underneath, I layered the backend so the model provider is a detail: pure domain types, use-cases that depend on protocols rather than vendors, and the adapters at the edge. I put retrieval on Postgres with pgvector rather than a separate vector service, which leaves one fewer system to run.
