Freelancer Overview

I have hands-on experience in creating and refining high-quality datasets for large language model (LLM) fine-tuning, with a strong focus on prompt engineering, data annotation, and rigorous evaluation. My work involves designing structured prompt-response pairs, developing rubric-based evaluation criteria, and systematically testing model outputs for hallucinations, bias, and consistency. I am skilled in Python, OpenAI APIs, and tools such as FastAPI, Redis, and CI/CD pipelines, which I have used to automate data collection, benchmarking, and QA processes. My background includes building internal dashboards for data transparency, collaborating with cross-functional AI teams, and delivering robust solutions in NLP, QA automation, and chatbot systems. I am passionate about ensuring data quality and alignment to drive reliable AI model performance.
