• Lead developer and software architect for cross-platform, high performant C++ audio/video processing pipeline used by multiple products throughout the company
• Created AVEngine, a C++ application used to transform and enhance media. It replaced numerous disparate legacy pieces in the Mediasite Video Platform, drastically improving performance and reducing bugs, and allowing.
• Implemented end-to-end hardware transcoding for NVidia and Intel
• Converted a large (170,000 lines not counting external dependencies), mature, Windows only C++ codebase to be cross platform with Linux
• Created a SmartRendering algorithm to allow cutting, trimming, and splicing of videos without a full transcode
• Created an algorithm to build a custom bitrate ladder on a per file basis

• Led a team to maintain and enhance the C++ recording pipeline used by the Mediasite Recorder application
• Created a real-time preview of captured data using WebRTC, including on-the-fly compositing of multiple video streams, audio/video sync, and a custom hardware encoder that scaled based on the available bandwidth
• Converted the pipeline to use MediaFoundation instead of MainConcept, and then again to use the FFmpeg libraries
• Worked with AVerMedia to improve their drivers; iterated through 36 driver version over three years
• Took ownership of the Mediasite Recorder build process; reverse engineered the existing build infrastructure and rebuilt it from scratch on new hardware, reducing build times by 55%
• Re-organized and cleaned up the Mediasite Recorder code-base, going from 16 solutions to 1, resulting in 25% fewer files, 30% smaller installer package, an additional 40% decrease in build time

Madison, Wisconsin, United States

• Worked on the Mediasite Recorder application in C++ and C#
• Developed code in C++ to capture audio and video from a wide range of hardware capture devices, including AVerMedia, Datapath, and generic USB devices
• Helped consistently reduced crashes by an order of magnitude from one release to the next
• Wrote C++ HID code (using the Windows HID API), to interface with Delcom button and light devices to provide control and feedback for the Mediasite Recorder Application
