Event-Driven Architecture
Deep mastery of event sourcing, CQRS, pub/sub topologies, and asynchronous processing patterns. Move beyond the conceptual understanding of events into the operational reality — where ordering guarantees, idempotency, and schema evolution determine whether the architecture survives production.

Module 1: Event Sourcing
State is a projection of history. Event sourcing stores the history instead of the projection — and that changes everything about how you reason about data, consistency, and debugging.

Module 2: CQRS
Command Query Responsibility Segregation separates the write model from the read model. The systems that change state and the systems that query state have different requirements — and the architecture should reflect that.

Module 3: Pub/Sub & Async Processing
Publish-subscribe topologies and asynchronous processing patterns at production scale — where ordering, delivery guarantees, and back-pressure determine whether the system processes events or drowns in them.
