Overview
What it is
A production-grade Learning Management System backend that powers the full learning experience: enrolling learners, delivering course content, tracking progress, and running assessments.
The API surface spans 88+ REST endpoints across six core domains, served by Express and fully typed with TypeScript. Prisma sits over PostgreSQL as a typed data layer, with Redis for caching and sessions.
Two distinct authentication flows separate learners from administrators, each with scoped access — so the same platform safely serves students and the team managing content.

Full CRUD over courses, modules, lessons, and media for the content team.
Progress tracking
Per-learner progress recorded across modules and lessons to drive the learning journey.
Assessments & quizzes
Assessment workflows with question banks, submissions, and scoring.
Typed data layer
Prisma over PostgreSQL with migrations keeps the schema and queries type-safe.
Caching & sessions
Redis backs performance-sensitive reads and session state under load.
Documented API
Swagger / OpenAPI describes the full endpoint surface for consumers.
Validation & security
Zod schemas, auth middleware, and rate limiting guard every request.
