Cloud and Platform Delivery

• Build and operate solutions across AWS and/or Azure and hybrid environments.
• Use Infrastructure as Code and automated configuration management.
• Deploy containerised workloads using Kubernetes and/or OpenShift.
• Contribute to CI/CD and GitOps pipelines.
• Apply secure configuration, resilience, and cost-conscious engineering practices.

Production Engineering and Quality

• Build automated functional, integration, security, and resilience tests.
• Apply OWASP, identity and access-management, and dependency controls.
• Implement logs, metrics, traces, and service-level objectives.
• Support incidents, root-cause analysis, and remediation.
• Maintain operational documentation and runbooks.
• Drive measurable improvements in quality, reliability, and delivery performance.

Team and Client Contribution
