• Reduced AWS Monthly costs by 50% by cleaning up unused AWS resources (EC2, AMI and S3), downsizing EC2 and RDS classes, downsizing volumes according to the usages and implementing Dynamic Jenkins nodes. Thus, saved over $30,000 per month over Amazon cost
• Implemented Dynamic Executor allocation for Jenkins to distribute 200 executors for more than 200 applications each leveraging 5 executors. Thus saved $200,00 on Cloudbees license cost.
• Led teams to architect, design, develop and implement Cloud solutions encompassing multiple specializations, platforms and technologies.
• Created RACI charts for onboarding 7 applications and collaborated with multiple external teams.
• Trained L1/L2 team to provide 24x7 support to Application teams..
• Upgraded CICD application including Jenkins, Bitbucket, Jira and Nexus and migrated them across AWS accounts
• Developed a common AMI for all Jenkins Nodes that’s been used by 200 different applications. This reduced time to onboard new applications and facilitated regular update of system patches and adding and updating new Softwares
• Created user managed KMS keys and encrypted the s3 buckets and EC2 volumes
• Automated onboarding applications to use CICD tools like Jenkins, Bitbucket and Nexus
• Automated AMI Backup and Clean up strategies of EC2 instances across AWS accounts
• Developed Kibana dashboard to illustrate the Jenkins Executor hourly usage
• Designed and implemented SSH key rotations for git users and Jenkins slaves
• Developed CI Support Jenkins pipelines to generate reports on Jenkins nodes. This include AWS meta data, list of software installed on the node, etc. This gave clear picture of the nodes to the Application Development team and reduced CICD tickets considerably.
