- Implement automated unit, integration, component, and contract testing.
- Integrate application components with CI/CD pipelines and GitOps deployment workflows.
- Build, package, and deploy applications using Docker and Kubernetes.
- Implement application logging, monitoring, distributed tracing, dashboards, and alerting using Dynatrace.
- Troubleshoot production issues and perform root-cause analysis across application, integration, data, and infrastructure layers.
- Conduct code reviews and enforce engineering, security, performance, and maintainability standards.
- Collaborate with architects, product owners, quality analysts, data engineers, DevOps engineers, and other developers.
- Use Windsurf and other AI-assisted engineering tools to accelerate development, refactoring, automated testing, troubleshooting, and technical documentation.
