About
I’m a Cloud Infrastructure and DevOps Engineer with 4+ years of experience building secure, scalable AWS environments and automating day-to-day operations. I enjoy designing reliable cloud architectures, improving deployment speed, and keeping production services stable through strong CI/CD practices and Infrastructure as Code.
In my roles, I’ve worked extensively with AWS services like EC2, VPC, IAM, ECS, Lambda, RDS, S3, Route 53, and CloudWatch, and I’ve delivered repeatable infrastructure using Terraform and AWS CloudFormation. I also support microservices and containerized workloads with Docker and ECS, build standardized AMIs with Packer, and provide production support, monitoring, and incident resolution to ensure operational excellence.

Configured SSL/HTTPS for Tomcat servers and AWS load balancers, created custom standardized AMIs using Packer, and supported Dockerized microservices on ECS. Provided 24/7 production support, collaborated across teams to troubleshoot issues, and contributed to incident resolution and root cause analysis.
Implemented and managed AWS infrastructure using Terraform and CloudFormation for development, testing, and production. Managed EC2 instances, Auto Scaling Groups, Application Load Balancers, multi-AZ deployments, and VPC networking. Built CI/CD pipelines using Jenkins, GitHub Actions, and AWS Code Pipeline for automated build, test, and deployment workflows. Deployed containerized applications using Docker and ECS with rolling and blue/green strategies. Monitored and optimized AWS costs via right-sizing and cleanup, and implemented centralized monitoring/logging with CloudWatch, Datadog, Splunk, and Grafana. Enforced IAM security best practices and supported compliance initiatives aligned with SOC2 and ISO 27001.
Assisted with provisioning AWS resources using Terraform and CloudFormation templates. Supported deployment and maintenance across development and testing environments, including EC2, Auto Scaling Groups, and Application Load Balancers with basic multi-AZ configurations. Helped with AMI creation, patching, Linux/Windows administration, and OS hardening. Managed S3 lifecycle policies, EBS snapshots, and backup schedules for cost optimization and disaster recovery. Configured CloudWatch logs and alarms, supported IAM permission management, and maintained infrastructure documentation.
