Patterns I reach for, and how the pieces fit together.

Clean Architecture

Concentric layers with dependencies pointing inward. The domain stays independent of frameworks, UI, and I/O.

Commands and queries take separate paths, letting the write model guard invariants while read models optimize for the screen.

Bounded contexts isolate models. Aggregates enforce consistency boundaries and communicate through domain events.

Producers publish events to a broker; independent consumers react asynchronously, decoupling workflows.

A hub pushes updates to connected clients over a persistent connection, with a backplane for horizontal scale.

An API gateway routes to focused services, each owning its data store — independently deployable and scalable.
