Freelancer Overview

I am an experienced AI Trainer with a strong background in data annotation, labeling, and model evaluation for machine learning and large language models. Over the past three years, I have worked with leading platforms like Scale AI, Appen, and Lionbridge, where I trained and evaluated LLMs, developed and refined prompts, and performed quality assurance to ensure high data accuracy and compliance with safety guidelines. My work has contributed to projects in NLP, content moderation, and multilingual AI model training. I am skilled in critical thinking, communication, and adapting to fast-paced remote environments, consistently delivering high-quality results and exceeding productivity benchmarks. My technical foundation in computer science supports my ability to understand complex project requirements and collaborate effectively with engineering teams to enhance AI systems.
