Freelancer Overview

I have hands-on experience in AI evaluation and search relevance, with a strong background in ensuring the quality, accuracy, and usefulness of machine learning outputs. At InnoData Inc., I worked as a Search Relevance Rater, where I assessed query results and optimized ranking quality to improve user search experiences. With Telus Digital, I served as an E-commerce Merchant Rater, reviewing product listings and ensuring accurate category alignment, pricing relevance, and cultural context for international markets. Most recently, at Welocalize and also Alignerr, I worked as a Result Evaluator and AI Response Checker, where I reviewed AI-generated outputs for accuracy, coherence, and user alignment, providing detailed feedback to refine model performance. Across all these roles, I’ve developed a keen eye for detail, strong analytical judgment, and the ability to evaluate content objectively against guidelines. My experience has given me a deep understanding of how to bridge the gap between human expectations and AI responses, ensuring that systems deliver reliable, context-aware, and user-friendly results.
