About this course
Why students take this
Where frontend ends, backend begins. This course is for students who want to understand how the data layer actually works — not just call an API and hope. We build real services from scratch with Node.js + Express, learn SQL the way a senior would, and ship them behind a proper auth layer.
By the end you will have built a small SaaS backend end-to-end: signup + login, role-based access, REST + JSON, a Postgres schema you're proud of, and a deployment that survives real traffic. You'll also know how to debug a slow query, write a meaningful test, and read someone else's codebase without flinching.
What you'll master
- Node.js, Express, async/await, error handling the right way
- PostgreSQL — schema design, indexes, joins, migrations
- REST APIs, JWT auth, request validation, rate-limiting
- Docker basics — running services locally + on a VPS
- Logging, monitoring, and how to read production errors
