Experience
EDA Migration to AWS
I technically led a project to migrate around 2,000 hosts to AWS. I wrote Terraform and Ansible code to automate the migration process. The code incorporated provisioning of Amazon EC2 instances, storage, load balancer, networking, security groups, S3 buckets, secrets, and parameters management and monitoring. The project's second phase is meant to build a cloud-native platform that completely runs on HashiCorp Nomad, Consul, and Vault. The setup and configuration are only done via code run under CI/CD pipelines running under TeamCity and Jenkins.
CMB Digital Transformation
The project is to migrate CMB applications written in Java and Node.js from the legacy platform to the CMB Digital Platform running under Pivotal Cloud Foundry and Mulesoft.
My responsibilities in the projects included:
1. Onboarded new projects into the CMB Digital Platform (Pivotal Cloud Foundry PCF, Mulesoft API Manager, GitHub, Jenkins)
2. Managed automated CI/CD process in an agile environment using different tools like Jenkins, Nexus, and custom scripts.
3. Set up monitoring dashboards in AppDynamics and Splunk
4. Built dashboards to monitor the platform, inventory, and issues tracking (custom-built dashboard using scripts).
5. Acted as lead engineer and provided training and guidance to new joiners in the UK, India, and China
In this project, I created many dashboards in AppDynamics to simplify the monitoring of the platform and also created a custom dashboard to manage cost per application using shell scripts and HTML.

Credit Risk Impact Analysis
I joined the team with the primary goal of improving the credit risk impact analysis process. Historically, the process took 10-15 days to complete, with many manual steps in between. I built multiple scripts and monitors, so the process was entirely run and complete in 8-10 hours, with the ability to run multiple processes in parallel. The whole run was automated without any manual intervention required.
My responsibilities included:
• Setup and manage ten isolated parallel environments used to run the impact analysis processes.
• Manage and support Symphony grid environments used by the runs to ensure the right versions are consistently set up per environment
• Improve utilization of all environments which resulted in an overall cost reduction of 30%
