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 development of new features that were deemed unworkable in the old code• 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• Added tracing to identify bottlenecks that runs in production without performance overhead• Created automated memory leak tests• Maintained comprehensive documentation, including developer, end-user, and architecture and dataflow diagrams

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
