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 was created 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
• Onboarded new projects into the CMB Digital Platform (Pivotal Cloud Foundry PCF, Mulesoft API Manager, GitHub, Jenkins).
• Managed automated CI/CD process in an agile environment using different tools like Jenkins, Nexus, and custom scripts.
• Set up monitoring dashboards in AppDynamics and Splunk.
• Built dashboards to monitor the platform, inventory, and issues tracking (custom-built dashboard using scripts).
• 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 platform's monitoring and a custom dashboard to manage cost per application using shell scripts and HTML.

Credit Risk Impact Analysis

I joined the team to primarily improve 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 finished 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
• Set up and manage 10 isolated parallel environments for 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%.

DevOps Implementation in Healthcare

http://rhythm360.io/

Managed and maintained multiple environments as the senior DevOps engineer, ensuring proper setup, configuration, availability, and HIPAA compliance.

I maintained an existing Docker swarm cluster and built further environments using Terraform code. I also built and maintained the data analytics platform based on Tableau and set up multiple CI/CD workflows on GitHub Actions to simplify microservices builds, tests, and deployments.

I used multiple AWS services and various other tools like Sentry, Grafana, Vanta, and Helm. I built different Amazon Machine Images for Windows and Linux instances using Packer to automate a new clinic setup fully. I migrated the PostgreSQL database across various environments and set up AWS DMS tasks to feed specific data sets into Tableau for data analysis. I also executed, supported, and monitored alerts using Prometheus, Datadog, and Amazon CloudWatch.
