Intermediate Clojure for Java Engineers

Build intermediate Clojure skill after Java by practicing data transformation, namespaces, macros, build tooling, testing, interop, REPL workflow, and deployment judgment.

Use this track after the foundations material, when basic syntax is no longer the blocker and engineering judgment becomes the real work. The emphasis is on moving Java habits into idiomatic Clojure shapes: values over mutable objects, namespaces over class folders, data pipelines over service-method chains, and REPL feedback over long compile-run loops.

Learning area	What to practice	Java habit to revisit
Data transformation	Sequences, reducers, transducers, and state primitives	Treating every transformation as a mutable collection loop
Code organization	Namespaces, dependencies, modules, and build tooling	Mapping package structure directly to class ownership
Production workflow	Testing, interop, deployment, profiling, and REPL debugging	Waiting for full application cycles before validating behavior
