Project description:
"I already have the React front-end live; now I need the Supabase + TypeScript muscle behind it. The web app compares tender and quote documents, so the core of your job is to turn uploaded PDFs into structured data, store that data efficiently, and expose endpoints that let the front-end run fast, accurate comparisons.

What you’ll build
• Secure user authentication and role-based authorization using Supabase Auth and row-level security.
• A well-indexed Postgres schema that can grow with millions of documents yet stay snappy.
• Serverless functions (TypeScript) that:
 – accept PDF uploads,
 – extract text reliably,
 – normalise and store the results, and
 – return comparison metrics and highlighted diffs on demand.

Acceptance criteria
1. A new user can sign up, verify, and log in; unauthorised calls are blocked.
2. Uploading a PDF triggers text extraction with >95 % accuracy on common tender layouts.
3. Given two stored documents, the compare endpoint returns a JSON diff within 2 s for files <10 MB.
4. Database queries stay under 100 ms for the same workload on the free Supabase tier.
5. A short README covers local setup, env vars, and sample curl calls.

If building clean, test-covered backend logic in Supabase and TypeScript is your thing, let’s talk." (client-provided description)
