Freelancer Overview

I have experience supporting AI training and data labeling projects involving text, image, audio, and document annotation. My work includes data categorization, image and object labeling, text classification, sentiment analysis, audio transcription, speech validation, document annotation, data validation, quality assurance, and adherence to detailed annotation guidelines. I am proficient at identifying patterns, maintaining consistency across large datasets, and delivering accurate, high-quality annotations that improve machine learning model performance. I have also worked with AI-assisted workflows and productivity tools, including large language models (LLMs), prompt engineering, Google Colab, APIs, and workflow automation platforms. I am experienced in following project-specific instructions, meeting quality and productivity targets, conducting quality reviews, and adapting quickly to new annotation standards. My analytical background in industrial chemistry has strengthened my attention to detail, problem-solving ability, and commitment to producing reliable, accurate datasets for AI development.
