I joined as part of the original ad engineering team that developed Twitch's server side ad insertion tech, SureStream. As the team grew, I became the expert on the existing client side ad experiences that our teams became responsible for. The Ad Supply teams came to own all of the viewer and broadcaster experiences, and I lead multiple efforts to streamline implementations, as well as implement observability into how our products (not just our services) performed. Multiple services I proposed and helped to launch help decide who should see an ad at the right time and deliver the right ad experience, at Twitch scale

I was a major contributing developer on: http://liu.edu/ http://gct.com/ http://virtuawoman.org/ http://yardsmarts.com/ http://sokolovelaw.com/ http://maybelline.com/Yardsmarts works off a central Article Catalog, which contains most of the content for the site, among other sites in the Multi-Site install. This resulted in the site requiring dynamic page loading based on the URL, which is uncommon in Sitecore. I created an OnSave event handler for the Sitecore Content editor to place articles' details into the Lucene index, and also wrote the algorithm to retrieve the article based on the Section and sub section that the article should live on. In addition to the commenting system on VirtuaWoman, I also optimized the C# code that interacted with Lucene.Net to dramatically increase the speed on a poorly performing section of the site, which provided an order of magnitude increase in response time.I am the lone Rails Developer on Ducky Guidance, our data-driven note system for guidance counselors. Ducky Guidance allows guidance counselors to manage their students and notes to take advantage of powerful reporting, and eliminate paper notes. Counselors can manage their students via groups that they either manually manage, or via dynamic groups, which group students based on common attributes. Counselors can add notes to individual students, or groups of students. Ducky Guidance also allows counselors to categorize and tag their notes, to enable powerful reporting.I manage our numerous servers and network. We have a number of different VMs hosted on VMWare ESXi. We run Ubuntu and Windows side by side, with environments ranging from PHP and MySQL to ASP.Net and SQL Server to Rails and PostgreSQL. We run both Apache and Nginx for our various linux projects.

I redesigned and implemented the SQL database used for our section's test executive. The redesign provided data integrity via foreign key relations, constraints and indexes that the prior design previously lacked. I also implemented a workflow design in the database that was used by the web interface the section used for data entry.After the redesign, I implemented the API for the database using Entity Framework. The entities were broken down into similar types, which dictated the workflow the entity would need to go through. I used interfaces to reduce the workflow code needed to validate and perform the sign offs.The Asp.net site I designed and implemented acted as the data entry interface for the SQL databased utilized by my section. I designed a workflow mechanism to make sure any data entered was signed off by the right managers and technical experts. I utilized Entity Framework to provide the ORM for the website, and used WebForms (due to the knowledge domain of others who would maintain the site as well) to implement the site.After realizing that some of the more complex relations prevented some pages from loading in a timely manner, I designed and implemented a web service and jQuery scripts to loaded the related data on demand with AJAX, creating a fast and clean web interface
