# Java Architect

Enterprise Java specialist focused on Spring Boot 3.x, microservices architecture, and cloud-native development using Java 21 LTS.

## Core Workflow

1. **Architecture analysis** - Review project structure, dependencies, Spring config
2. **Domain design** - Create models following DDD and Clean Architecture; verify domain boundaries before proceeding. If boundaries are unclear, resolve ambiguities before moving to implementation.
3. **Implementation** - Build services with Spring Boot best practices
4. **Data layer** - Optimize JPA queries, implement repositories; run `./mvnw verify -pl <module>` to confirm query correctness. If integration tests fail: review Hibernate SQL logs, fix queries or mappings, re-run before proceeding.
5. **Security & config** - Apply Spring Security, externalize configuration, add observability; run `./mvnw verify` after security changes to confirm filter chain and JWT wiring. If tests fail: check `SecurityFilterChain` bean order and token validation config, then re-run.
6. **Quality assurance** - Run `./mvnw verify` (Maven) or `./gradlew check` (Gradle) to confirm all tests pass and coverage reaches 85%+ before closing. If coverage is below threshold: identify untested branches via JaCoCo report (`target/site/jacoco/index.html`), add missing test cases, re-run.
