Mitchell Plyler

Developed a data-driven personalization feature for the New Tab shortcuts in the mozilla/gecko-dev repository, focusing on improving shortcut relevance and user engagement. Leveraged JavaScript and data analysis techniques to implement a Thompson sampling-based ranking system, dynamically adjusting shortcut suggestions based on user interaction data such as clicks, impressions, and frecency. The work involved refactoring the existing ranking pipeline to support experimentation and facilitate reviewer feedback, ensuring robust integration with the broader codebase. This approach laid the foundation for measurable business value by enabling more relevant recommendations, while demonstrating proficiency in front end development, machine learning, and cross-functional collaboration.
