I’m a Cloud DevOps Engineer with three AWS certifications, including AWS DevOps Engineer Professional and AWS Solutions Architect Associate. I focus on designing multi-tier AWS architectures and turning them into reliable, automated delivery pipelines.

In my work, I build infrastructure with Terraform and CloudFormation, using reusable modules, cross-stack references, and SSM Parameter Store to keep environments reproducible. I design for high availability with Multi-AZ patterns, read replicas, session caching, cross-region replication, and failover routing.

I’m especially strong in secure, observable operations. I implement least-privilege IAM, secure networking with VPC security groups and NACLs, apply KMS encryption, and use WAF and Shield where needed. I monitor with CloudWatch logs/alarms/dashboards, add X-Ray for distributed tracing, and automate rollback and incident notification with Lambda and SNS.

I also optimize delivery and cost without sacrificing reliability. I’ve built end-to-end CI/CD pipelines with GitHub Actions and AWS CodePipeline/CodeBuild/CodeDeploy, supporting blue/green, canary, and in-place deployments. On the container side, I use Docker with ECR and deploy workloads to Amazon ECS, while applying cost optimization practices like right-sizing, Reserved Instances, Savings Plans, and AWS Budgets.
