Freelancer Overview

I am a skilled AI Trainer and Software Developer with a strong background in artificial intelligence, data science, and software engineering. My experience includes designing and training AI models for tasks like natural language processing and image classification, as well as managing data labeling and annotation processes to ensure high-quality training datasets. I have worked with tools such as TensorFlow, PyTorch, and Scikit-learn, and have delivered solutions across finance, retail, and education domains. My hands-on approach to building and deploying machine learning models, combined with expertise in cloud platforms like AWS and Azure, allows me to effectively contribute to AI projects that require accurate, well-curated training data. I am passionate about leveraging my technical and analytical skills to support innovative AI solutions and drive real-world impact.

Acted as a Subject Matter Expert (SME) to train and refine Large Language Models (LLMs) specifically for complex programming tasks. My role involved writing high-quality Python and JavaScript code snippets to serve as 'Golden Answers' for Supervised Fine-Tuning (SFT). I performed rigorous RLHF (Reinforcement Learning from Human Feedback) by ranking model-generated responses based on logic, security, and Big O efficiency. I specialized in identifying 'hallucinations' in code and providing corrected logic for complex algorithms, ensuring the model adhered to modern software engineering best practices.
