• Cloud Computing:
  Hands-on experience with cloud services and architectures, especially AWS, Azure, or GCP.

• Monitoring & Logging:
  Familiarity with monitoring and logging tools (e.g., Prometheus, Grafana, ELK stack, Nagios, Splunk) for performance tracking and troubleshooting.

2. Security

• Security Best Practices:
  Understand how to implement security in both development and operational workflows, including vulnerability testing in CI/CD pipelines and data encryption.
