I built automation in Terraform to securely manage federation across multiple AWS accounts in an ever-growing environment in a HIPAA-compliant setting. I also trained corporate IT in the usage and maintenance of the code for a successful handover.
The environment was used by dozens of teams for a total of over 400 engineers, encompassed over 15 accounts, and grew constantly.

I built the entire infrastructure to support a Django-based web application for an insurance brokerage agency. I leveraged CloudFormation and Puppet to automate infrastructure provisioning and configuration management. I also integrated access management with firm-wide Active Directory and automated code deployments onto servers running Nginx, uWSGI, and Django using AWS RDS and AWS ElastiCache.

I automated the provisioning and cancellation of a dozen different server software licenses for a hosting company consisting of over 500 virtualized and bare metal servers, saving significant work hours for both management and the IT team. I used Ansible and Python to automate API calls. I also performed server-side updates to achieve server-level idempotency based on business logic captured in simple to understand and edit configuration files, empowering even non-technical staff to make licensing changes.

I automated rotation and centralized management of sensitive credentials across a fleet of hundreds of bare-metal and virtualized (VMware, KVM, Xen) servers in a programmatic way. I also consolidated management credentials for administrative users, IPMI, and iDRAC into one secured, centralized, highly-available, programmable vault, decreasing company risk and satisfying security requirements.

I used Packer and Ansible with AWS EC2 to automate the infrastructure for a Django-based web app and transition it from in-place code deployment to image-based deployments that could leverage autoscaling, thereby achieving fault tolerance and reliability. The transition to Packer-based AMIs simplified change management, testing, and security while ensuring that the system was constantly in a predictable state.

I containerized a Python web app using Docker, simplifying both local development, testing, and deployments across multiple environments. I also introduced continuous security scanning of Docker images into the CI/CD pipeline using Trivy, increasing visibility into security vulnerabilities and encouraging more frequent security updates to be incorporated into the development cycle.
