1. Designed a machine learning system capable of automatically extracting relevant and specific information from a given URL, resulting in a ~70% reduction in human effort.2. Created a user-friendly machine learning annotation tool that streamlines the process of creating training datasets, making data collection and cleaning more efficient. As a result, the machine learning models built with cleaner data achieve higher performance.GitHub link: https://github.com/SachinKalsi/html_tag_annotator
