At Fannie Mae, I played a key role as a Cloud/DevOps Engineer, leveraging my expertise in both AWS and Azure to streamline operations and optimize infrastructure. I developed ETL processes and data models using tools like SAP Data Services and Informatica, ensuring efficient data flow within the organization. I actively managed AWS cloud resources including EC2, S3, RDS, EBS, and Elastic Load Balancers, implementing cost-saving measures through automation and resource optimization. Additionally, I planned and migrated data storage solutions (Blob, Table, Queue) on Azure.I spearheaded the creation of a robust CI/CD pipeline using Jenkins, Chef, and TeamCity, automating build, deployment, and release processes for various projects. I implemented configuration management tools like Ansible and Chef, including designing and deploying Cassandra rings in secure, multi-AZ VPC networks within AWS. I configured Single Sign-On (SSO) and multi-factor authentication leveraging Azure AD, ensuring secure access for users.Containerization: I embraced Docker technology, creating custom container images, managing networks, and virtualizing applications for efficient resource utilization. I actively participated in application deployments, maintenance, and troubleshooting across both AWS and Azure environments. I utilized scripting languages (Batch, Shell, WMI, WSH) for automation tasks, while also setting up CloudWatch monitors and alarms for proactive infrastructure monitoring. All This experience allowed me to demonstrate a strong ability to collaborate with various teams, automate processes, and leverage cloud technologies effectively to achieve organizational goals.

As a DevOps Engineer Collaborated with cross-functional teams at Cigna to implement and optimize DevOps practices within AWS environments. Automated build and deployment processes for various applications, leveraging tools like Jenkins, AWS CloudFormation, and Python scripting. Integrated CI/CD pipelines with testing tools (Selenium, Cucumber, SonarQube) to ensure code quality. Developed and managed containerized applications using Kubernetes and ECS/EKS. Utilized Tableau for data visualization and reporting. Contributed to production release management, providing DevOps solutions to enhance efficiency and automation.

As a Devops engineer. I successfully managed the configuration of servers on Amazon EC2 using Linux AMIs to support specified applications. I developed custom Chef cookbooks to automate components not available in the marketplace, significantly improving our CI/CD pipeline, cloud architecture, and deployment processes. I provided expert support for various AWS services, including EC2, EBS, S3, CloudWatch, CloudFront, IAM, Security Groups, Auto-Scaling, AWS CLI, and CloudWatch monitoring. I utilized Chef for continuous delivery, rewriting recipes for new environments and automating weekly releases with ANT/Maven scripting. I integrated Chef cookbooks into Jenkins jobs to automate the deployment process and configured Jenkins build jobs with AWS deployment pipelines using plugins like Jenkins-EC2 and Jenkins-Cloud Formation. My technical expertise spans AWS, Linux, Ruby, Perl, Shell Scripting, Python, JBOSS, WebLogic, Apache, and other relevant tools.
