Course modules
- 01~13min
HTTP & REST — what every endpoint should do
Five HTTP verbs, eight status codes, and a handful of conventions. Get these right and your API is instantly more professional than 80% of what's in the wild.
- 02~14min
Databases — relational vs NoSQL, indexes, and the N+1 trap
PostgreSQL is the right answer for most applications. This module shows you why, when to pick something else, and the single most common bug in beginner backend code.
- 03~15min
Authentication — sessions, JWTs, and password hashing
Most auth tutorials online are wrong or incomplete. This module shows you what production teams actually use, why, and the security mistakes that cause real breaches.
- 04~14min
API security — the OWASP basics every backend dev must know
Most data breaches in the news are caused by a small handful of mistakes. This module covers them all and shows you the one-line fixes that prevent each one.
- 05~12min
Caching — the four levels that matter
There are exactly four places to cache. Knowing what to put where (and the one rule about invalidation) fixes most slow-API problems.
- 06~12min
Async work & queues — moving slow work out of the request
If your endpoint takes more than 500ms because of email/PDF/external APIs, you're doing it wrong. This module shows you the queue pattern that fixes it.
- 07~12min
Logging, monitoring, and the things that wake you at 3am
If you can't see what your service is doing, you can't fix it. The right logs and metrics turn a 3-hour incident into a 30-second fix.
- 08~13min
Deployment — environments, secrets, and shipping safely
The difference between a junior who breaks production and a senior who never does is process. This module shows you the pipelines and patterns that make deploys boring (the highest compliment).
