Patterns are taught as refactoring moves, not buzzwords. You will evolve a single codebase from an anemic service to clearer modules, introduce domain events with idempotency notes, and sketch read models where they actually reduce load—not everywhere.

Cohort questions
Examples use Spring pieces where helpful, but concepts transfer.
Pairs are welcome; pricing is per learner seat.
We do not certify you as an architect—this is practice with feedback, not a title.

Outbox session mirrored what we needed for inventory sync—diagrams I made landed in our RFC.
Anti-pattern gallery stung a bit—in a productive way.
