PROFILE
Mitchell Plyler
During July 2025, Michael Plyler developed a data-driven personalization feature for the New Tab shortcuts in the mozilla/gecko-dev repository. He refactored the shortcut ranking pipeline to incorporate user interaction data, such as clicks and impressions, along with frecency, enabling dynamic and relevance-driven recommendations. By implementing a Thompson sampling-based ranking algorithm using JavaScript, he improved the potential engagement and relevance of shortcut suggestions. His work required close collaboration with code reviewers and integrated data analysis, front end development, and machine learning skills. The changes laid the foundation for measurable business value by supporting experimentation and ongoing improvements to user experience.
