Freelancer Overview

I have hands-on experience training and evaluating AI models through multimodal data annotation and response quality review. In my recent work with Outlier AI, I evaluated AI-generated outputs for accuracy, reasoning quality, policy compliance, and completeness across text and image-based tasks. This involved identifying hallucinations, logical inconsistencies, and safety concerns, applying detailed annotation guidelines, and providing structured feedback to improve model performance. I consistently maintained high accuracy standards while meeting productivity targets in a fast-paced review environment. My background in strategy and analytics further strengthens my effectiveness in AI training and data labeling. I bring strong pattern recognition, data validation, and quality assurance skills, supported by advanced Excel and working SQL knowledge. I am experienced in structuring complex information, ensuring consistency across datasets, and applying analytical rigor to improve data integrity. This combination of annotation precision, analytical thinking, and process discipline allows me to deliver reliable, high-quality training data that improves model performance and reliability.
