• Monitor and improve MTTR (Mean Time to Recovery) and MTTD (Mean Time to Detect) across services to enhance operational resilience.
• Design scalable AWS-based systems, including multi-region deployments and disaster recovery strategies.
• Develop reusable, versioned Terraform modules and maintain scalable Ansible configurations.
• Design and maintain reliable CI/CD pipelines using tools like Harness.
• Build and optimise observability systems using Dynatrace and other platforms for proactive monitoring and root cause analysis.
• Lead incident response efforts, conduct root cause analysis, and implement process improvements.
