- 2. • TeamCity Continuous Integration Engine. 250+ Windows and Linux Agents, running mostly on VMWare with some AWS overflow. • Puppet Enterprise, Heira with Zookeeper for configuration management of test databases, TeamCity agents, and versioned release installations of the application for QA. Puppet with rspec and rake for Test Driven Development. • Chocolatey & Powershell to provide an interface into Nuget Windows package manager for Puppet on Windows (https://chocolatey.org/). • PowerCLI scripts for provisioning into vSphere, and for template management. • Packer and, Terraform for provisioning into Amazon Web Services to create VM templates (or AMI’s) and running instances ready for bootstrap from Puppet. • Artifactory – Artifact repository and local Puppet and Chocolatey Forge. • Jira, Confluence and Agile Development process, Scrum and Kanban. • Subversion and Git. Replicated Subversion repositories in India and Rancho Cordova CA. • Oracle, MySQL, SQLServer, Postgres databases. • Apache Tomcat, Apache ActiveMQ, • Ant, Make and Gradle. Accomplishments - Participated in the design, creation and implementation of an automated provisioning and configuration management infrastructure using Puppet, Hiera, Zookeeper, Chocolatey, Powershell, and PowerCLI to create and manage hundreds of servers used in the testing, building, and deploying of application releases. o Am a constant contributor in the upgrade plan(s) including the creation of Terraform and Packer modules to provision servers in the Amazon cloud allowing us to plug them into our Puppet infrastructure. - Participated in the design, creation and setup of the Continuous Integration Project. o Am a constant contributor in the upgrade and improvement of all aspects of the CI/CD process, including refactoring the creation of artifacts from Ant to Gradle. Restructuring the process to identify subcomponent artifacts that can be split up and then only recompiling the modules that have changes going in, coordinating it all with Gradle dependencies and caching into Artifactory or directly from the CI engine - Wrote Puppet modules and windows scripts that generate Chocolatey modules called by the Puppet modules to install versioned releases of the Navis TOS application into QA and developer environments. This allows us to deliver fully installed and configured releases of the application into a clustered multi-hosted virtual environment. Saving many hours spent by QA and others installing and configuring the application. - Also providing branch management for multiple repositories all with inter-referencing external dependencies. o Wrote a script to create code freeze branches in Subversion for 3 separate repositories maintaining dependencies with each other and managing the separation from the source branches. This ended a process whereby which developers we not able to check in to the active development branch during a code freeze period while a release was prepared for and passed final QA testing. The new process saved many developer hours. - Rewrote our production application installers using Install4J, replacing the existing Installanywhere.
