Freelancer Overview

I have strong experience in AI training and data labeling, especially in Natural Language Processing (NLP). I have worked on building and improving machine learning models for tasks like text classification and summarization. My work includes data annotation, checking data quality, and evaluating model performance to make sure results are accurate and reliable. I am also skilled in Python, SQL, and tools like PyTorch and TensorFlow. I have worked as an AI Research Scientist, where I developed advanced AI models and published research papers. I also have experience improving training systems to reduce costs and increase efficiency. I understand AI safety and bias, and I focus on creating fair and high-quality training data. My background in data science and ongoing PhD in AI make me well-prepared for AI training roles.
