• Configure and maintain Deployments, Services, ConfigMaps, Secrets, Ingress, health probes, resource limits, and Horizontal Pod Autoscaling.

• Use Helm charts or equivalent deployment packaging and troubleshoot application issues across Kubernetes clusters.

4. Messaging and Event-Driven Architecture

• Design asynchronous, event-driven integrations using Kafka, RabbitMQ, Azure Service Bus, ActiveMQ, or equivalent platforms.

• Build resilient message producers and consumers with idempotency, retries, dead-letter queues, ordering, and error-handling strategies.

• Monitor message processing, diagnose failures, and support reliable delivery across distributed services.

5. Performance, Reliability, and Support

• Optimize application performance, scalability, security, resilience, and availability.

• Implement structured logging, metrics, distributed tracing, dashboards, and alerting.

• Troubleshoot production issues, perform root cause analysis, and implement corrective and preventive actions.

6. CI/CD, Quality, and Governance

• Build and maintain CI/CD pipelines using Azure DevOps, GitHub Actions, Jenkins, or equivalent tools.

• Write unit, integration, contract, and automated tests using appropriate .NET testing frameworks.

• Participate in code reviews, architecture reviews, threat modeling, release readiness, and technical documentation.

• Follow secure coding practices, Agile delivery methods, SDLC controls, and enterprise engineering standards.
