Freelancer Overview

I am an experienced AI evaluation and digital operations specialist with a strong background in data annotation, search quality rating, and model output validation. I have contributed to projects such as Polly, Lighthouse, and Cumulus, where I performed AI output evaluation, annotated training data, and assessed content quality and guideline compliance. My expertise includes interpreting query intent, evaluating localization and cultural context, and producing structured, evidence-based reports. I am proficient with web-based evaluation and annotation platforms, internal task management systems, and productivity tools for documentation and reporting. I consistently maintain strict confidentiality, adhere to project guidelines, and deliver high-accuracy results in remote and asynchronous environments. My approach is detail-oriented, audit-ready, and focused on continuous improvement in AI training data quality.
