CI/CD: Own build and deployment pipelines (GitLab CI/GitHub Actions/Jenkins), versioning, and artifact management.
Quality: Write unit/integration tests (JUnit/Mockito/Testcontainers); maintain code quality via linters and code reviews.
Observability: Implement logging, metrics, and tracing (CloudWatch, OpenTelemetry, Prometheus/Grafana, ELK).
Security & Compliance: Apply secure coding, manage secrets (AWS Secrets Manager/SSM), and least-privilege IAM.
Collaboration: Work closely with Product, QA, DevOps/SRE to deliver features end-to-end.
