- Optimize application performance, throughput, memory management, and database query execution.
2. Quality Assurance & Engineering Best Practices
- Write clean, modular, and maintainable code adhering to enterprise coding standards and SOLID principles.
- Develop comprehensive automated unit, integration, and component tests using frameworks such as JUnit, Mockito, PyTest, or Unittest.
- Maintain high code coverage and resolve static code analysis findings (e.g., SonarQube, security vulnerabilities).
3. CI/CD & DevOps Automation
- Integrate applications with modern CI/CD pipelines (e.g., GitHub Actions, Jenkins, Tekton, Harness).
- Containerize services using Docker and support deployments onto container orchestration platforms (e.g., Kubernetes / Red Hat OpenShift).
- Participate in environment setup, automated deployment validation, and release management.
4. Collaboration & Agile Delivery
- Actively participate in Agile ceremonies including Sprint Planning, Daily Standups, Backlog Refinement, and Retrospectives.
- Collaborate with business analysts, technical leads, UI/Frontend engineers, database administrators, and QA teams.
- Conduct constructive peer code reviews and contribute to technical documentation (architecture diagrams, API specs in OpenAPI/Swagger).
5. Production Support & Operational Excellence
- Assist in triage, root cause analysis (RCA), and remediation of Level 3 production issues.
- Monitor application health and diagnostics using observability tools (e.g., Prometheus, Grafana, Splunk, OpenTelemetry).
