Freelancer Overview

During my work at Mavn AI, I led data-labeling projects from start to finish, crafting clear annotation guidelines for both code (like function classification and bug tagging) and text (entity extraction and sentiment labeling). I used tools such as Labelbox and custom interfaces to train and mentor a team of annotators, implemented QA processes that cut errors by 30%, and collaborated closely with ML engineers to refine ambiguous cases—ensuring high-quality datasets that sped up our model training and boosted real-world performance
