• Managed cost and performance monitoring of resources and applications using AWS CloudWatch, creating alarms, and configuring notifications for metrics such as EBS, EC2, ELB, RDS, S3, and SNS. • Developed reusable infrastructure components using Terraform, promoting reusability, consistency, and maintainability across multiple projects. • Integrated Terraform with CI/CD pipelines (Jenkins, GitLab CI/CD, or AWS Code Pipeline) to automate infrastructure provisioning for efficient deployments. • Designed, configured, and deployed highly available and fault-tolerant AWS architectures for healthcare applications, focusing on auto-scaling, load balancing, and capacity monitoring. • Analyzed logs and performed root cause analysis for various issues daily. • Implemented and managed S3 buckets, user accounts, access permissions, and IAM policies. • Configured VPC networking components (Private Link, Direct Connect, Transit VPC, VPC Peering) for secure data transfer and connection to other AWS services and accounts. • Utilized network health monitoring tools like CloudWatch and Logic Monitor. • Wrote cron jobs to monitor SQS queue size and notify administrators. • Built and secured Amazon EC2 instances using security groups and network access control lists (NACL). • Implemented security measures, including SIEM systems for log analysis and threat detection. • Focused on continuous integration and deployment, leveraging tools like Bitbucket and Docker for efficient infrastructure management and application releases. • Designed roles and groups using AWS IAM for access management. • Leveraged AWS services such as EC2, auto-scaling, and VPC to build secure and scalable systems. • Designed and implemented secure network architectures, enforcing access controls, and utilizing encryption protocols to ensure network security best practices.

• Implementing a Continuous Delivery framework using Jenkins, Chef, Maven in Linux environment • Developed Chef Cookbooks to manage systems configuration. • Developed Ansible scripts for an automated server provisioning and Docker images, reducing the time between provisioning and deployment from over 3 hours to less than 10 minutes. • Help educate enterprise customers on the value proposition of AWS and participate in deep architectural discussions to ensure solutions are designed for successful deployment in the cloud. • Consult with relevant development and operation organizations to guide the use of enabling technologies and services to accommodate project and operational needs • Utilized Docker for streamlined deployment, creating Docker images and utilizing container orchestration platforms like Kubernetes for efficient container management and scalability. • Configured NACL, security groups, and WAF for application and VPC network security. • Designed and implemented monitoring metrics and logging systems using CloudWatch, CloudTrail, Data Dog, and Logic Monitor. • Developed high availability, backup, and recovery strategies for applications and databases.

● Written build and deployed automation scripts (ansible) which deployed to ~100 servers in our distributed system, interacting with multiple load balancers, allowing us to serve the traffic or user requests with zero downtime and high-availability, fault-tolerant systems. ● Extensive experience in automation of Software Configuration Management (SCM) including repository setup, branching, merging, release management processes. ● Automated common, repeatable tasks at large scale using chef and Ansible. ● Involved developing and modifying new and existing environments to support newer versions of Infrastructure stack, and build/deployment management using tools like Chef, Jenkins, Git, AWS, etc. in windows and Linux platforms. ● Test, Review and merge Pull Requests in GitHub. ● Managing users, organizations and repositories or projects in Version Control System such as Git and SVN. ● Building CI pipelines in Jenkins by creating the master-slave architecture and integrating the Jenkins with various tools such as Git, Sonarqube, Junit, Selenium, etc. by using different types of plugins available in Jenkins. ● Worked with TeamCity as the continuous integration tool to meet the internal requirements of the organization for one of the applications. ● Work with Build and Release teams to enhance the current process to implement better software packaging and delivery by automation using Jenkins & chef. ● Created instances (VMs) in AWS with required stack of infrastructure for application and QA teams to execute and test their applications or products. ● Configured AWS Virtual Private Cloud environment and networking inside the VPC. ● Worked with Glacier to archive old files as needed. ● Administered databases using RDS, MySQL and Dynamo DB in AWS. ● Used AWS CLI to create new instances and manage existing instances.
