API
Inventory API with a caching layer
A JWT-protected inventory API that caches item reads, so repeated lookups never hit the database twice.

01The problem
What it had to solve.
Inventory endpoints get read far more often than they get written. Serving every one of those reads from the database is the easiest performance problem to avoid and the most commonly ignored.
02The build
How it was put together.
- Item resource exposed through a DRF viewset with registration and token endpoints
- Read-through cache on item lookups — check the cache, fall back to the database, populate on miss
- Custom token-obtain view, so authentication behaviour is explicit rather than default
- Registration endpoint separated from authentication, each with its own serializer

What it demonstrates
- Caching applied where the read/write ratio actually justifies it
- Cache invalidation thought about at write time, not left to expiry
- A small API kept deliberately small, with clear boundaries
