ABOUT RAHAT B.
Senior System Administrator with a strong foundation in AWS infrastructure, cost optimisation, and access management. I specialise in supporting engineering teams by automating cloud environments using Terraform, resolving complex CI/CD and infrastructure issues, and ensuring security, compliance, and performance across AWS workloads. With hands-on experience in provisioning, patching, and monitoring services like EC2, RDS, S3, IAM, CloudFront, and more, I work at the intersection of cloud operations and developer enablement. I regularly manage temporary and permanent IAM access using infrastructure as code, help debug deployment problems, and reduce cloud waste through smart cost visibility tooling.
