Freelancer Overview

I am an AI Trainer and Data Scientist with over 3 years of experience in data labeling, model evaluation, and large language model (LLM) training. My expertise spans reinforcement learning with human feedback (RLHF), supervised fine-tuning (SFT), and prompt engineering, where I have contributed to creating high-quality datasets and refining model outputs for accuracy, coherence, and alignment. I have worked on projects that required evaluating AI-generated responses across technical, mathematical, and natural language processing tasks. My background in computer science and applied mathematics has given me a strong foundation in probability, linear algebra, and optimization, which I apply when assessing reasoning quality and problem-solving accuracy. I am also experienced in developing evaluation criteria, scoring outputs, and generating prompts that challenge models to perform at a higher standard. With proven skills in NLP data annotation, mathematical reasoning, and AI evaluation, I bring both technical expertise and attention to detail. I am fluent in English (C1), Urdu, and Hindi, which allows me to contribute effectively to multilingual and cross-domain projects. Passionate about advancing Generative AI, I aim to leverage my experience to improve data quality and ensure reliable, ethical model performance.
