Freelancer Overview

I am a detail-oriented Data Annotation Specialist with over three years of hands-on experience in labeling and preparing high-quality training data for AI and machine learning models. My background includes working with diverse data types such as text, images, audio, and video, and I have contributed to projects involving LLM reasoning chains, API logic, and complex UI labeling. I am proficient in industry-standard annotation tools like CVAT, LabelMe, Roboflow, LandingLens, and Google AI Studio, as well as Python and automation workflows. My engineering education has equipped me with strong analytical and problem-solving skills, and I excel at breaking down complex information, resolving documentation ambiguities, and collaborating with cross-functional teams to optimize data pipelines for AI development. I am passionate about leveraging my technical expertise to support innovative AI solutions across domains such as computer vision and natural language processing.
