Redis
An in-memory data store used for caching and fast key-value access.
What it is
Redis keeps data in memory as keys and structured values, which makes reads and writes fast enough to sit in front of a slower primary store.
How I learned it
I worked with Redis as part of a production Node and Express backend during my internship at Aude.ai.
How I use it
I use it where a request needs data faster than a round trip to the primary database is worth.
Concepts I work with
- Key-value storage
- Caching
- Expiry and TTL
- In-memory data structures
What I learned
A cache is only as useful as its invalidation strategy is clear.

Projects using Redis
I haven't published a project using Redis yet — it's something I use in work that isn't shareable, or that I'm still building.
