Participate in the Production Release and guide the Production teams in their deployment.

Inspected the infra setup and architecture of the new launch of applications in the AWS environment.

Performed AMI rehydration on the EC2 instances with the latest enhancements from AWS, updated the Cloud Formation Templates with the new AMI and ensured this new AMI created new stack for AWS EC2 instances in Prod and DR AWS regions.

Completed an extensive product overview and scrutinized the application launch scripts and other cloud formation templates (CFT) in AWS to ensure the application setup in the lower environments like QA or Dev have the best policies and practices pertaining to the configuration of Amazon S3, ELBs, EC2, EBS, Route53 and RDS resources on the AWS cloud before their infra setup and go live in Production environment.

Signed off the application launch in Production and monitored the application go live and enthusiastically participated during the go-live of the applications in Prod AWS and worked with the Prod Support teams to fix issues noticed during the launch.

Supervised the production releases and certified them to follow the best policies and procedures laid down by the organization both under the Agile and ITIL methodologies, thereby reducing the prospect of multiple unwarranted deployments.

Coordinated with the Dev, infra and Application teams for smooth launch of the application in Prod.

Reviewed the Release cycles of the applications and conducted the Release Strategy meetings to schedule the monthly releases and prioritize the release components.

Assisted the technical teams for the Production deployments by opening Change tickets and used the previous experience of the application to provide technical competence during production releases.
