Freelancer Overview

I have hands‑on experience training AI systems across text, image, audio, and multimodal datasets, with a strong focus on accuracy, consistency, and guideline adherence. My work includes NLP tasks such as classification, rewriting, sentiment analysis, and LLM response evaluation, as well as computer vision annotation involving image tagging, object identification, and visual QA. I’m skilled at interpreting complex instructions, refining labeling approaches, and ensuring high‑quality outputs that directly improve model performance. I bring a data‑driven approach shaped by my master’s program in Business Analytics & Data Science, where I work extensively with Python, R, SQL, and statistical modeling to understand patterns, reduce noise, and improve data quality. This analytical background strengthens my ability to identify edge cases, evaluate model behavior, and apply structured reasoning to complex annotation tasks. Combined with 25 years of leadership experience, I excel in quality assurance, workflow optimization, and maintaining consistency across multi‑annotator projects, the areas where precision and reliability matter most.
