WORK HISTORY
Aws Platform Engineeer @HSBC
London, GB
Designed, deployed, and managed AWS infrastructure for production workloads using Terraform and Terragrunt, introducing a modular structure for reusability and environment consistency.Built and maintained EKS clusters for microservice deployments with managed node groups, auto-scaling, and namespace-based access controls.Automated EKS add-on deployments (ALB Ingress Controller, ExternalDNS, Metrics Server, Datadog Agent) using Terraform Helm providers.Developed Lambda-based automation for routine platform operations such as:Auto-remediation of non-compliant resources (public S3 buckets, untagged instances)Dynamic DNS registration for ECS and EKS servicesRotating database credentials via Secrets ManagerManaged multi-account networking with Transit Gateway and shared VPC patterns.Implemented CI/CD pipelines in GitHub Actions for infrastructure and application deployments, leveraging reusable workflows, OIDC roles, and matrix deployments.Led the migration of EC2-based SFTP servers to AWS Transfer Family with custom authentication via API Gateway + Lambda + DynamoDB.Configured Datadog monitoring and log forwarding from CloudWatch, ECS, and EKS, setting up alerting and dashboards for service health, latency, and failed logins.Established cost governance using tagging enforcement, automated cleanup scripts, and Slack-based cost alerts.Designed a unified CloudFront + WAF + S3 solution for static content hosting with centralized SSL via ACM.Introduced lifecycle and “create_before_destroy” strategies in Terraform to ensure zero downtime during updates.Key Achievements:Reduced AWS infrastructure costs by 30% through Spot usage, better sizing, and cleanup automation.Improved EKS deployment success rate to 99% via pre-deploy health checks and rolling updates.Shortened environment provisioning time from hours to under 20 minutes with Terraform automation.Built a self-service Terraform module library used across multiple teams and accounts.

ABOUT SRIRAM OJJA
I’m an AWS Platform Engineer with around 5 years of experience designing, automating, and operating secure and scalable cloud platforms.I specialise in building infrastructure through Terraform, managing container platforms like EKS and ECS, and driving automation using Lambda and GitHub Actions.My work mainly focuses on platform reliability, automation, and cost efficiency. Over the past few years, I’ve helped teams modernise their infrastructure by replacing manual deployments with reproducible Terraform pipelines and by introducing observability with Datadog and CloudWatch.I enjoy simplifying complex systems — whether that’s turning a set of AWS resources into clean IaC modules, building a reusable CI/CD workflow, or writing a Lambda to automate routine operations.Outside of work, I keep learning about infrastructure security, Kubernetes internals, and new ways to make platforms more efficient and self-healing.
