Freelancer Overview

I am an experienced data annotation and AI model evaluation specialist with over four years supporting large-scale AI training and QA projects. My work spans LLM benchmarking, RLHF evaluation, prompt engineering, and structured data labeling for both text and multimodal datasets. I have deep expertise in designing and auditing annotation workflows, building gold standard datasets, and ensuring inter-rater reliability using tools like Labelbox, ScaleAI, Remotasks, and internal QA dashboards. My background includes hands-on annotation of text, image, and audio data, as well as rigorous quality assurance for supervised fine-tuning, preference ranking, and classification tasks. I am skilled in Python, basic SQL, and data structuring (JSON/XML), and have contributed to open-source datasets in NLP and code-switching. I thrive in remote, cross-functional environments and am recognized for my precision, adaptability, and ability to translate complex evaluation findings into actionable insights for engineering and research teams.
