Java Architect

This is a solid enterprise Java skill that covers the full stack from domain modeling through data access, security, and reactive endpoints. It walks you through a structured workflow with verification checkpoints at each stage, like running mvnw verify after security changes to catch filter chain misconfigurations. The reference system is well organized for different contexts (WebFlux, JPA optimization, Spring Security with OAuth2/JWT), and the code examples show practical patterns like avoiding N+1 queries and properly configuring stateless JWT auth. The workflow enforces 85% coverage thresholds and includes specific troubleshooting steps when tests fail. Aimed squarely at Spring Boot 3.x and Java 21, so it will push you toward records, sealed classes, and modern patterns rather than legacy approaches.
