PROJECT:

• Successfully migrated a monolithic application to a microservices architecture on Amazon EKS, leveraging Docker, Jenkins, and Terraform. The project resulted in improved scalability, better resource utilization, and reduced time to market for new features.
• successfully migrated a legacy on-premise application to AWS cloud, leveraging services like EC2, S3, RDS, and Lambda to improve scalability, reliability, and performance. Implemented a CI/CD pipeline using AWS CodePipeline, CodeBuild, and CodeDeploy, resulting in faster deployment times and increased developer productivity.

• Proficient in using Amazon Web Services (AWS) for implementing, deploying, and managing infrastructure, applications, and services.
• Experience in working with various AWS services such as EC2, S3, ECS, ECR, EKS, VPC, RDS, IAM, CloudFormation, CloudWatch, and Lambda.
• Managed container orchestration using Kubernetes, creating and managing clusters, deployments, and services.
• Hands-on experience with Docker for containerizing applications, optimizing images, and managing containers.
• Utilized Terraform for infrastructure as code (IAC) to automate provisioning and management of AWS resources.
• Implemented continuous integration and continuous deployment (CI/CD) pipelines using Jenkins for automated build, testing, and deployment processes.
• Leveraged Ansible for configuration management and automated deployment of applications and infrastructure components.
• Proficient in using Git for source code management, branching, merging, and resolving conflicts.
• Monitored application performance and system health using various monitoring tools such as Prometheus, Grafana, and ELK stack.
• Skilled in scripting languages such as Python, Bash, and PowerShell for automating tasks and implementing custom solutions.
• Achieved a 30% reduction in infrastructure costs and a 40% improvement in application performance and scalability.
