Work History

Architect - Cloud Engineering

IBS Software
Bangalore
10.2021 - Current
  • As a systems consultant, I am responsible for provisioning infrastructure based on the Hosting document provided by the Customer's Enterprise Architect.
  • I play a key role in our team to ensure a smooth application go-live by cross-verifying the complete environment and checking if monitoring and APM tools, as well as ServiceNow integration, are enabled.
  • I have created multiple SOPs and RCAs and provided the required knowledge transfer (KT) to our team and the support team.
  • I work closely with the Architect during Application Architectural discussions.
  • I handle IAM roles and IAM policy management to achieve various use cases.
  • I have deployed multiple AD servers and our own SFTP, which are deployed on EC2 servers.
  • I prepared multiple Python scripts to automate day-to-day activities for the Support team, such as volume clean-up of available states, and AMI and snapshot clean-up with conditions to ignore current running instance AMI from ASG, currently used, and the latest LT AMI.
  • I created a custom shell script to perform system-side checks before go-live. This activity used to take 30 minutes per server, but with the script, it now takes less than 5 minutes.
  • To enable centralized login, I created cross-account IAM roles, Lambda functions, and EventBridge to create alarms for instances in ASG.
  • I have made numerous updates to the existing platform to create additional resources like SES, SNS, AWS Backup Vault, IAM roles, and policies using Terraform.
  • I implemented a service creation approach in Linux-based servers to start applications upon successful EFS mount completion, with all artifacts stored in EFS.
  • I guide the team in resolving system-related issues when they get stuck.
  • I implemented the EFS CSI driver, as suggested by AWS, to mount EFS to PODs in EKS.
  • I led a team of 7 engineers to successfully migrate over 60 EKS clusters.
  • I regularly updated Jenkins pipelines and created projects and applications in ArgoCD.

  • Responsible for provisioning environments (Dev, PreProd, and Prod) using the DevOps Jenkins tool and CloudFormation templates to create IAM roles and KMS keys, collaborating with the AWS security team for deployment.
  • Conducted a POC on open Kubernetes by creating a Jenkins server and implementing custom shell scripts to automate infrastructure deployment.
  • Provisioned pods, services, deployments, daemon sets, secrets, and HPA based on CPU utilization.
