Freelancer Overview

Analytical and detail-oriented AI professional with hands-on experience in data annotation, AI response evaluation, and quality assurance across text and multimodal datasets. I have performed high-volume annotation across text, image, audio, and video data while maintaining over 95% accuracy, and consistently evaluated AI-generated outputs for relevance, correctness, and instruction adherence. My work includes ranking model responses, conducting image and video comparisons, annotating with timestamping techniques, and assessing text-to-image and text-to-video alignment. I am highly skilled at identifying edge cases, detecting inconsistencies, and applying structured guidelines to ensure scalable, high-quality datasets. With a background in Economics and Software Engineering, I bring strong analytical thinking and a systems-oriented approach to AI training workflows. I excel at managing complex, multi-step tasks efficiently, handling over 100 tasks daily, while maintaining precision and consistency. I also contribute to improving annotation quality by refining guidelines, verifying logical reasoning in model outputs, and providing actionable feedback. My combination of speed, accuracy, and attention to detail enables me to deliver reliable data that supports the development of high-performing AI systems.
