A mock-test app for one exam candidate, built as a real monorepo anyway.

A Gujarati-first mock test app for the GSSSB CCE prelims, built for a single aspirant. The questions are not the product. The analysis after the paper is, which is why the scoring lives in its own package with no imports and its own unit tests.

A Turborepo with three apps and seven packages: the Expo app she sits papers in, a Hono API, and a TanStack Start admin panel for the question bank. A CI check enforces that the on-device schema stays a subset of Postgres, so the phone can never drift ahead of the server.

The supporting scripts matter as much as the apps: a CSV importer that rejects rather than warns, a command line tool that assembles and publishes a paper, and a Python extractor that pulls questions out of the commission own PDFs.

Engineering notes

scoring: a pure package with no imports and its own unit tests
validation: one Zod layer shared by the CSV importer and the API boundary
check-schema-parity: CI fails if the device schema drifts from Postgres
Pooled and direct Postgres URLs kept apart, because PgBouncer cannot serve transactions
