Developed modular Terraform and ArgoCD workflows so clusters, networking,
and workloads stay fully declarative and version-controlled.
Optimized managed and self-managed node groups with taints, tolerations, and
capacity types to keep latency-critical and batch workloads isolated and cost-
efficient.
Extended cluster CIDR blocks through ENIConfig automation to remove IP
exhaustion blockers during high-traffic releases.
Automated worker-node patching with eks-node-rotation, SSM health checks, and blue/green safeguards to minimize downtime during upgrades.

Alertmanager, routing Slack alerts with templated runbooks for actionable
incident response.
Integrated Fluent Operator, Elasticsearch, and Kibana to deliver centralized,
queryable audit trails for platform and application logs.
Hardened ingress by layering AWS WAF, AWS Shield, and custom Nginx OAuth
flows to remediate penetration-test findings.
Engineered AWS Transit Gateway topologies that connect multi-VPC estates while
preserving segmentation and inspection points.
Established Infrastructure-as-Code guardrails by refactoring Terraform modules
and ArgoCD app-of-apps patterns for repeatable platform rollouts.
Collaborated closely with frontend, data engineering, and data science teams,
