  Research, design and development of large scale classification systems for various abuse detection teams. I was responsible for setting direction, technical leadership, contributing to roadmaps and visions, growing and scaling the capabilities of the team. Specific efforts are listed below. • Researched and developed machine learning ideas for high-impact improvements to abusive account detection. Identified fundamental limitations of the existing approach and resolving these by introducing using Graph Neural Nets, transfer learning and autoencoders. These resulted in large increases in recall and opened up more avenues for improvement. • Drove usage of classification scores generated by my team. The scores are used in hundreds of places and forms the basis for basically all abuse detection in Facebook. Supported teams to make optimal use of the scores and collaborated to ensure stability and adversarial robustness. • Architected solutions in collaboration with specially created infrastructure teams to migrate to a graph neural network and optimize resource usage to save thousands of servers.
