Tech Stack: Java 21+, ${framework}, Maven/Gradle. Use records for immutable data transfer objects. Use sealed interfaces for restricted type hierarchies. Constructor injection for all dependencies. No field injection. Use Optional for nullable return values. Never return null from public methods. Streams: prefer for transformations. Use traditional loops for side effects. Naming: classes PascalCase, methods camelCase, constants UPPER_SNAKE_CASE. Package structure: by feature, not by layer. Exception handling: checked for recoverable, unchecked for programming errors. Logging: SLF4J + Logback. Use parameterized messages, not string concatenation. Tests: JUnit 5. @DisplayName for readable test names. Testcontainers for integration. Build: reproducible builds. Lock dependency versions. No SNAPSHOT in production.
