The KCOE — Kikwiflow Certified Orchestration Engineer credential recognizes Java developers who can **model, implement, and operate** business processes with Kikwiflow, the embedded orchestration (workflow) engine for Java 21 and Spring Boot. Holders design the process graph visually in Kikwiflow Craft, implement every step as an ordinary Spring bean — `TaskHandler`, gateway resolvers, timer and retry policies —, test those components with JUnit and Mockito, deploy the process inside their own Spring Boot application with no external engine to run, and operate live instances through the REST management API and Kikwiflow Monitor — diagnosing incidents down to the instance, the step, and the variable.
