Data quality and ML-focused rater improving AI training and search relevance.
What I'm looking for
I’m a data-quality focused professional who helps make AI systems more reliable by reviewing, labeling, and validating datasets used to train AI models. In my current role as a Data Quality Annotator at Mercor, I ensure accuracy and consistency across data types (video, audio, and text), including Italian localization projects and creation of audio recordings.
Previously, I’ve worked as a Data quality specialist at SuperAnnotate, designing engineering solutions to optimize data annotation processes and collaborating with development teams to improve annotation tools using Python and cloud technologies. I’ve also supported Generative AI multilingual guardrails at Lionbridge by creating AI prompts and responses and managing tasks, and I’ve strengthened my quality-evaluation expertise through Search Quality Rater work at Telus International AI and Ads Quality Rater experience at Welocalize—assessing relevance, usefulness, and guideline compliance, then submitting detailed feedback that improves algorithms.
