• Developed in house release application for deploying to AWS infrastructure. The deployment orchestrater consisted of a C# application that used WinRM connections to distribute and execute server-side Python and PowerShell scripts.• Developed continuous delivery pipeline to internal testing servers. The pipeline consisted of self-hosted git repositories, Jenkins pipelines, and Chef scripting for configuration.- Documented release workflow and procedures with a key focus on pre and post conditions. Documenting these conditions defined explicit criteria to allow for the creation of automated processes.- Participated as a mentor in the first DocuTAP U Internship program. Through this opportunity, I was able teach core programming concepts such as object-oriented design, encapsulation, idempotent systems, and logarithmic complexity to a student intern.
