– Build VPCs, private subnets, routing strategies, and network segmentation aligned with strict organisational security controls (SCPs, no-internet architectures). – Take solutions from low-level design (LLD) through to deployment and operational readiness—ensuring everything is production-grade, auditable, and supportable. – Design and manage EKS-based workloads, integrating backend services (FastAPI), frontends, and databases (Aurora/Postgres) within tightly controlled networks. – Enable internal service communication using VPC endpoints, private DNS, and controlled routing—eliminating reliance on NAT Gateways or public access. – Build and maintain Terraform modules for consistent, repeatable deployments across environments, troubleshooting failures caused by SCP and policy constraints. – Resolve complex infrastructure failures (e.g., EC2 access loss, SSM misconfigurations, DNS issues) using low-level recovery techniques such as volume reattachment and helper instances. – Enforce encryption, IAM least privilege, secure secrets management, and audit-ready configurations across all deployed services. – Work closely with DevOps, AI/ML, and application teams to ensure infrastructure aligns with application requirements while maintaining security and compliance. – Leverage AI tools to accelerate scripting, debugging, and infrastructure automation, improving delivery speed without compromising quality. – Produce detailed LLDs, architecture diagrams, and operational guides to support governance, onboarding, and long-term maintainability.

– Led AWS cloud security architecture and delivery – Implemented Terraform-based infrastructure and CI/CD pipelines – Designed secure multi-AZ environments and IAM strategies – Eliminated SSH using SSM Session Manager
