• Built a team of DevOps engineers and created a git workflow and overall pipeline to produce stable infrastructure as code solutions to serve thousands of customers on a daily basis.• Migrated Frontend UIs, Backend API, and Databases from on-premises Openstack installation to multi-VPC AWS environments.• Built new pipeline from the ground up converting from Jenkins with puppet deploy process to an immutable infrastructure model using Terraform, Ansible, Jenkins, and Consul.• Fully integrated existing application code base into the immutable infrastructure model to include all secrets stored in vault, blue/green deploys of heavily trafficked customer facing sites, and centralized logging infrastructure on the backend for developers to see the results of their changes in as close to real-time as possible.• Built Jenkins pipelines to easily compile and deploy new container infrastructure to Kubernetes.

- Build a reliable and flexible AWS-based cloud environment. - Ensure that all systems are built and managed via Chef to allow for running a large enterprise environment with as few administrative resources as possible.- Ensure that monitoring (Nagios), authorization (FreeIPA), and security tools (openVAS) are tightly coupled with the Chef configuration management server to ensure newly built servers are configurated automatically with as little administrator input as possible.- Create and maintain Chef cookbooks for all aspects of building an enterprise computing environment in AWS.- Cookbook include haproxy, mod_security, katello, nagios, apache, nginx, postgresql, mysql, drupal, freeIPA, git, subversion, mongodb, and many other common components of modern web stacks.- Experienced in many components of AWS to include: VPC, EC2, S3 (Glacier), IAM, SES, Cloudfront, Route53, and Elastic Beanstalk in particular.- Implement continuous deployment using Jenkins to quickly deploy developer code at the touch of a button or automatically depending on the project.

- Install and configure VMware vCloud Infrastructure stack, to include vCloud Director, vCloud Automation Center, and vCenter Orchestrator.- Automate VM catalog for customers to choose type of VM(s) to include for their application with the VMware vCloud Infrastructure.- Design and build proof of concept vCloud implementation for a large government enterprise.- Build out and deploy a virtualized platform in order to migrate services off of old hardware and software platforms.- Fully integrate the Puppet Configuration Management software with the virtualized platform in order to manage the day to day operations of the virtual servers in the environment.- Created a set of custom Puppet Modules in order to fully secure the entire virtualized platform according to STIG standards, and maintain security through configuration management items.- Followed the Software Engineering Life Cycle to create a fully documented system from requirements gathering through the system design and testing. - Wrote the System Security Plan (NIST format) for the newly created platform and ensured proper security throughout the environment.

- Integration of RHDS, RHCS, and Red Hat Clustering services into a large scale distributed environment. - Ensure all COTS and GOTS applications can use RHDS for access credentials to provide a single point to manage user and application accounts for the entire site.- Created scripts and solutions for security and configuration management.- Setup and configure Red Hat Network Satellite to kickstart many servers for initial build out and to maintain current patch levels across all servers.- Provide on-site support for a large scale government client spread across multiple geographic locations for all Red Hat COTS products.
