Freelancer Overview

I am a certified data scientist with hands-on experience in data labeling, annotation, and validation for AI model training, particularly in NLP and generative AI domains. In my role as a Data Classification and AI Evaluator at Sama, I have contributed to optimizing machine learning models by ensuring high-quality structured data, monitoring performance metrics, and maintaining data integrity for ethical and scalable AI development. I am skilled in Python, SQL, TensorFlow, PyTorch, and Scikit-learn, and have worked on projects involving dashboarding, predictive modeling, and workflow automation. My background also includes building sustainability dashboards, automating data pipelines, and mentoring others in data science, giving me a strong foundation in both technical execution and collaborative problem-solving for AI and data-driven projects.
