• Lead the migration of services to Kubernetes in AWS (EKS) and GKE, enhancing application modernization. • Build a healthcare application platform in Azure using AKS, focusing on secure networking and CI/CD pipelines. • Write modular Terraform code for multi-cloud infrastructure management, ensuring scalability and security best practices. • Manage a team of two engineers, coordinating delivery and enforcing DevOps standards across environments.

Designed multi-region infrastructure for payment systems processing $50B+ daily transactions. Built GitOps pipelines enabling safe payment system deployments. Architected autoscaling based on transaction volume during peak banking hours. • Designed multi-region Kubernetes infrastructure on AWS and GCP for payment processing systems. Infrastructure handles $50B+ in daily transactions and is required to maintain service availability across multiple availability zones. Implemented cross-region failover enabling rapid recovery if infrastructure fails. • Built GitOps deployment pipeline using ArgoCD and GitHub Actions – standardized payment system deployment across teams, replaced manual configuration with infrastructure-as-code, enabled safe updates without coordination overhead. • Implemented autoscaling based on transaction volume and payment throughput – infrastructure scales during morning peak banking hours and international transaction waves, optimized resource utilization vs. generic CPU-based scaling. • Established real-time monitoring using Prometheus, Grafana, AlertManager – visibility into payment success rates, transaction latency, fraud detection metrics, incident response within minutes. • Designed disaster recovery procedures – cross-region replication, automated failover testing, documented runbooks ensuring rapid recovery if primary infrastructure fails.

Automated patching for 1000+ EC2 instances across regions. Built modular infrastructure enabling rapid deployment for clients. Designed compliance reporting for security audits. • Built AWS Systems Manager Patch Manager solution – automated patching of 1000+ EC2 instances across multiple AWS regions, eliminated manual patching overhead (teams previously spending weeks on quarterly patch cycles), reduced security vulnerability window. • Created modular infrastructure using AWS IAM, VPC, AWS Systems Manager – reusable components for secure patching environments, enabled rapid deployment for new clients. • Set up multi-pipeline CI/CD using GitHub Actions, GitLab CI, AWS CodePipeline – automated build and deployment, reduced manual deployment errors. • Developed Python automation tools with AWS Lambda – created custom patch compliance reporting tracking vulnerable servers, provided visibility for compliance audits.
