PROFESSIONAL SUMMARY:

• As an IT professional with 7+ years of experience mainly focused on providing infrastructure automation services within private and public cloud and also including experience in servicesbased on continuous delivery and buildwith cloud service like AWS in Windows and Linux systems.
• Experience in DevOps space which includes creating new environments, migration and maintained.
• Highly motivated and committed DevOps Engineer experienced in Automating, configuring and deploying instances on AWS cloud environment.
• Experience in branching, tagging and maintaining the version across the environments using GIT (Github, Bitbucket).
• Hands on experience with AWS Cloud Administration which includes services like: EC2, S3, EBS, VPC, ELB, AMI, SNS, RDS, IAM, Route 53, Auto scaling, Cloud Front, Cloud Watch, Cloud Trail, Cloud Formation, Security Groups.
• I have helped developers by setting up the infrastructure in the AWS dev. and QA accounts so that the developers can run their application using the architecture.
• Worked with the lambda functions setting up the server - less infrastructure facilitating developers so that they can run the code without worrying about the servers.
• Managed VMware and AWS resources in a Red Hat Linux dominant environment. Worked with developers to design highly available applications and automate deployments with CloudFormation and Terraform.
• Used Route 53 for setting up the hosted zones and the record sets so that the traffic from the user is reached to the specific service in the aws account.
• Have set up the networking for the application running in the ec2 instances. Including the sub-netting and VPC creation.
• Created NAT gateways for those instances so that they can reach the outer internet and download the latest software and the patching.
• Security groups and the Network ACLS are used for the protection of the ec2 instances at the subnet and instance level.
• Cloud watch logs have been setup for the lambdas, load balancers and all the possible places so that the debugging would be easy.
• Cloud-trail has been used to see what’s going on in the aws account.
• Played around with data-pipeline to export date form one service to another and in-turn made use of the EMR services.
• Used IAM to setup the users, groups, roles, policies and made use of the AWS managed policies, created custom managed policies, used IAM to create roles that give permissions to the lambda and ec2.
• Experience in building private cloud infrastructure of OpenStack, deploying through puppet and maintaining them in production.
• Good Exposure on Virtualization and Containers (Docker) and Kubernetes.
• Experience in working with container based deployments using Docker, Docker images, Docker file, Docker Hub, Docker Compose and Docker registry.
• Used Terraform to create and manage AWS infrastructure.
• Created API gateways so that the lambda functions can be invoked in a secure manner (not exposing them to the open internet). This included creating API keys to call the methods and created usage plans, custom domains so that the endpoints that we use are not that complicated.
• Extensively experienced in using Build Automation tools like ANT and Maven .
• Created S3 buckets for the storage which is the most reliable and elastic storage, have played around with s3 buckets in many areas, like, versioning, events, using the bucket policies and ACLS.
• Have set up the EC2 instances. (Linux, windows).
• Implemented Continuous Integration and deployment using various CI Tools like Puppet, Chef, Jenkins.
• Have set up the load balancers (Classic, application and networking) based on the use-case so that the traffic coming from the Route 53 can be distributed among the servers so that whole load is not taken by one server.
• Experience in setting up Weblogic Server domains across multiple data centers and strong understanding of active-active and active-passive architecture.
• Highly experienced in installing and configuring Apache to Weblogic plugin across various environments.
• Monitoring Health of Weblogic Servers in Production.
• Use Crontab to automate daily system administration tasks such as creating backups, synchronizing files, and schedule updates and involved in Linux administration.
