Flowable Platform — Core (Primary Skill)
▸ Flowable 6.x / 7.x: Flowable Engine, Flowable REST, Flowable Modeler, Flowable Admin, Flowable IDM — architecture, configuration, and operational management
▸ BPMN 2.0 mastery: all task types (user, service, script, send, receive, call activity, sub-process), all gateway types (exclusive, inclusive, parallel, event-based, complex), all event types (start, end, intermediate, boundary — timer, error, signal, message, escalation, compensation)
▸ CMMN 1.1: case plan model, stages, human tasks, process tasks, sentries, milestones — for adaptive/unstructured processes such as complaints handling and credit review
Process Integration with Microservices
▸ JavaDelegate / DelegateExecution patterns: Spring bean injection into delegates, transactional boundaries between process and service layer
▸ Flowable REST API: programmatic process start, task query/claim/complete, variable update, process instance migration — consumed by Backend Engineer's APIs
▸ Kafka integration: service tasks publishing domain events; boundary message events consuming Kafka topics for process correlation (e.g. KYC completed, payment settled)
Java & Spring Boot
▸ Java 17+: proficiency sufficient to implement delegates, listeners, DMN beans, REST clients, and unit tests independently
▸ Spring Boot 3.x: auto-configuration, Spring Data JPA (for process DB), Spring Security (task-level RBAC), Spring Web for REST task endpoints
Testing & Quality
▸ Flowable JUnit 5 support: FlowableRule / FlowableExtension, in-memory H2 engine for unit tests, process scenario assertions
▸ Scenario-based integration tests: drive process end-to-end with Testcontainers (Postgres + Flowable), mock service task delegates with Mockito/WireMock
Process Modelling Standards & Governance
▸ BPMN naming conventions, swimlane discipline, element ID standards, and documentation attributes — establish and enforce team guidelines
▸ Spec-Driven Process Development: author process spec documents (narrative + BPMN XML) and ADRs before implementation; align with OpenAPI specs co-authored with Backend Engineer
