Document parsing SaaS — from local tool to cloud service.

What I built

Software Engineering Intern (June – July 2026). Built the multi-tenant SaaS end to end: FastAPI + TanStack Start, public API, API-key management, org-scoped auth, and Stripe ledger billing — shipped as 13 reviewed PRs.

Moved the engine to AWS behind a CI accuracy gate (91.7% extraction quality) so nothing merges that degrades parsing.
