Freelancer Overview

I have hands-on experience in AI training data and data labeling through my work at Pareto AI, where I contributed directly to improving model quality and reliability. My responsibilities included annotating and reviewing large-scale datasets, evaluating model outputs against detailed rubrics, and providing structured feedback to help refine reasoning, accuracy, and consistency across tasks. What sets me apart is my strong attention to detail, ability to apply complex guidelines consistently, and comfort working with ambiguous or edge-case scenarios. With a technical background in software engineering, I bring a deep understanding of how models are trained and used in production, allowing me to deliver high-quality annotations that meaningfully improve AI performance.
