• Designed and implemented GitHub repositories to manage IAM roles and policies; integrated with AWS CodePipeline to automate permission updates, ensuring developers receive scoped access to the AWS Console.
  • Developed IAM roles and policies using VSCode based on project requirements, managed version control via GitHub, and followed CI/CD best practices with pull requests and approvals before deployment.
  • Created AWS architecture diagrams and, upon client approval, provisioned the required infrastructure using AWS CloudFormation templates.
  • Customized public Docker images by modifying Dockerfiles to meet project-specific needs and hosted the images in a private container registry.
  • Mounted Boomi API Gateway using Amazon ECS with Fargate by pulling the required Docker image from Docker Hub, storing the image in a private Artifactory repository, and deploying it in a serverless architecture to ensure scalability and security.
  • Set up Amazon ECS using Fargate to deploy serverless containers; created task definitions referencing Docker images and managed ECS services to maintain desired task counts.
  • Configured Application Load Balancer (ALB), created listener rules to route traffic to appropriate target groups, and registered ECS task IPs with the target groups.
  • Managed security groups by allowing necessary inbound IP ranges for ALB, EFS, and ECS to ensure secure communication across services.
  • Automated Docker image version updates (e.g., for Java upgrades) within CloudFormation templates and managed code promotion through production environments.
  • Stored one-time installation tokens as environment variables in ECS task definitions to securely deploy Boomi Molecules.
  • Automated secrets rotation in AWS Secrets Manager by developing a Lambda function, enhancing security and ensuring regular credential updates.
  • Developed an AWS EventBridge and AppFlow-based solution to receive notifications when standard/custom objects or platform events are updated in Salesforce.
  • Created platform events, custom objects, and associated custom fields within Salesforce to support real-time integration use case

• Launched and configured Amazon EC2 instances (both Linux and Windows) across multiple AWS regions, tailoring each setup to specific application requirements.
• Installed and configured security software on EC2 instances and managed EBS volume storage for high availability and performance.
• Provisioned infrastructure by building servers using AWS, including importing volumes, launching EC2 and RDS, configuring security groups, auto scaling, and deploying Elastic Load Balancers (ELBs) within Virtual Private Clouds (VPCs).
• Created and managed AWS IAM users for new projects, configured AWS CLI credentials, and managed S3 access permissions using CHMOD and ACLs.
• Created and maintained S3 buckets, defined bucket policies, and implemented IAM role-based access control for secure data management.
• Configured Amazon CloudWatch and SNS to set up monitors, alarms, and notifications for EC2 instances to ensure high availability and performance monitoring.
• Designed and managed VPCs, created subnets, configured inter-zone connectivity, and implemented network ACLs to block suspicious IPs/subnets.
• Administered DNS records using Amazon Route 53, ensuring accurate routing and high availability of hosted applications.
• Managed EC2 health checks, security groups, load balancers, AMI snapshots, and performed instance backups and restores using S3 volume snapshots and key pairs.
• Monitored production server health (CPU, memory, disk usage, and status checks) using Amazon CloudWatch, and deployed CloudWatch Agent on all servers to collect custom metrics.
• Performed patching and updates on both Linux and Windows servers, coordinating with the AWS Ops team to maintain compliance and security.
• Developed CloudFormation templates via AWS CLI to automate provisioning of infrastructure, including the deployment of AWS EMR Clusters
