Freelancer Overview

I am a passionate Python developer with hands-on experience in AI model evaluation, data annotation, and prompt engineering. My background includes systematically testing and benchmarking state-of-the-art language models such as GPT, Perplexity Sonar, and Gemini, focusing on code correctness, reasoning, and performance metrics. I have developed automated workflows for data collection and research using tools like n8n, FireCrawl, and RESTful APIs, and am skilled at logging and documenting results with PostgreSQL and Google Sheets. My expertise covers prompt engineering, reinforcement learning, and technical reporting, and I am committed to advancing practical AI applications through rigorous data labeling and model assessment.
