How the two wings fit together

01SQL first — every backend role assumes it. Then PostgreSQL as your default engine.

02Linux + Git + Docker — the DevOps base every deploy sits on.

03Specialize by need — NoSQL engines when data shape demands it; Kubernetes/CI-CD when scale does.

04Close the loop — monitoring and one cloud provider end-to-end makes you production-literate.
