Project Descriptions: AMI Compliance Auditing Framework: Led a team to design and implement an internal security tool to audit vulnerabilities in AWS AMIs across 350+ accounts in Citi’s AWS organization. The tool integrated with Terraform pipelines and reported non-compliant images to the security dashboard, enabling faster remediation and meeting audit requirements. Multi-Account Networking with Secure API Access: Designed and deployed a secure proxy layer for Citi’s AWS footprint (300+ accounts) using Transit Gateway, Site-to-Site VPN, and Azure Application Gateway. The proxy routed outbound traffic to third-party compliance APIs from trusted Citi IP addresses, ensuring regulatory alignment and secure data flow. GitOps-Driven Cluster Lifecycle Management: Architected a GitOps-based framework to manage 120+ Kubernetes clusters (EKS/AKS) across multiple AWS and Azure accounts. Implemented Helm, Flux, and RBAC policies to standardize deployments and security. This system reduced cluster drift, improved scalability, and enabled fully automated lifecycle management.
