Start with normalization so your schema avoids update anomalies before you optimize anything else.
Once the schema is right, indexing is what actually keeps queries fast as tables grow.
Decide how data reaches clients, REST and GraphQL trade off differently on caching, versioning, and over-fetching.
Cache-aside and write-through patterns absorb read load that would otherwise hit your database directly.
Every endpoint that touches SQL is a potential injection point; this is the baseline defense every backend engineer needs.
Understand how containers actually talk to each other before you deploy anything that depends on more than one service.
Load balancers are the first real scaling lever once a single server stops being enough.
