Infrastructure as Code & Automation: Implement and maintain infrastructure using Infrastructure-as-Code frameworks such as Terraform, ensuring reproducible, version-controlled, and auditable infrastructure provisioning and configuration management. Container Platforms & Orchestration: Design, deploy and operate containerized workloads using Docker and Kubernetes, optimizing cluster architecture, resource utilization, and high availability for production-grade environments. CI/CD & Release Engineering: Build and maintain robust CI/CD pipelines to automate build, test and deployment processes, enabling frequent, reliable and independent releases of platform and application components. Observability & Reliability Engineering: Establish comprehensive monitoring, logging and alerting using tools such as Prometheus, Grafana and centralized logging stacks, ensuring high platform reliability, rapid incident detection and efficient troubleshooting. Incident Management & Operational Excellence: Define and implement operational best practices, including incident response procedures, automated remediation strategies, and performance optimization to maintain platform stability and availability.
