Here is a concise summary of my key contributions:Within the AWS ecosystem, I effectively utilized various services such as EC2, ELB, S3, Elastic Block Storage, Elastic Beanstalk, VPC, SNS, IAM, and CloudWatch. I developed AWS CloudFormation templates to create custom-sized.Security was a top priority, and I enhanced it by leveraging AWS Security Token Service (STS) to provide temporary credentials to users for secure access to AWS resources. IAM integration with AWS services like S3 bucket policies and Lambda function policies allowed for fine-grained resource access control. To automate routine tasks and enable event-driven architectures, I set up CloudWatch Events to trigger AWS Lambda functions and other automated actions based on specific events.Automation was a key focus, and I developed AWS CloudFormation templates and integrated them with CI/CD pipelines using AWS CodePipeline and AWS CodeBuild.For data storage and failure mitigation, I built EBS volumes with snapshots, enabling data backup to S3 at specific intervals. CloudWatch was utilized to monitor resources like EC2, CPU, RAM, Amazon RDS DB services, and EBS volumes.Additionally, I created Chef Cookbooks for Apache Tomcat, Jenkins, and deployment automation installation and configuration.I leveraged Docker to manage images, AWS ECR for image storage, and Nginx as a reverse proxy and load balancer to enhance application scalability and high availability.In terms of cloud migration, I used AWS Database Migration Service (DMS) to migrate databases from GCP to AWS and implemented hybrid cloud environments that integrated both GCP and AWS services for specific use cases.To streamline continuous integration and deployment, I developed Jenkins Code Deploy plugin for AWS deployments, automated build processes, and managed Jenkins slaves for simultaneous task execution.Utilizing various scripting languages like Groovy, Perl, Bash, and Shell, I automated data import/export and system tasks.
