Served as Senior SRE and Kubernetes SME for Akamai Linode Cloud, managing production-grade platforms to support scalable microservices, and cloud-native workloads. Designed and maintained a highly available Kubernetes platform architecture, ensuring 99.95%+ service uptime, and minimizing infrastructure-related incidents across multi-environment infrastructure. Operationalized core SRE practices by defining SLIs, SLOs, and error budgets while reducing MTTR by over 50% through detailed runbooks, automated diagnostics, and incident response workflows. Led cluster lifecycle management and zero-downtime migrations, seamlessly executing Kubernetes upgrades, node rotations, cluster expansions, and control plane compatibility validations. Built reusable Infrastructure as Code (IaC) modules using Terraform to provision clusters, node groups, load balancers, and core networking/storage layers. Architected and optimized GPU-accelerated infrastructure for AI/ML workloads by leveraging NVIDIA CUDA and GPU time-slicing to maximize hardware utilization and efficiently share compute resources across dense microservices. Automated platform operations using Python scripting to eliminate manual toil for health validations, cluster auditing, and incident diagnostics. Designed and optimized CI/CD pipelines via Jenkins and GitHub Actions, embedding automated validation, security checks, and canary deployment strategies for microservices. Implemented a production-grade observability stack using Prometheus, Grafana, and Alertmanager to monitor cluster health, node saturation, and SLO compliance. Acted as a core responder for P1/P2 incidents, driving root cause analysis (RCA), traffic mitigation, emergency scaling, and post-mortem documentation. Mentored junior SREs and developers on Kubernetes production readiness standards, architecture best practices, and operational excellence.
