Freelancer Overview

I am a Python programmer and automation expert with practical experience in crafting custom scripts, handling intricate APIs, and creating AI-powered workflows. I am particularly adept at crafting end-to-end workflows that extract, parse, and clean structured data (JSON/CSV) for downstream processing, especially in sports data analytics. In addition to custom scripting, I have rich experience in the practical evaluation of Large Language Models, developing custom AI solutions, and workflow optimization for production-quality outputs. I am highly skilled in data processing libraries such as pandas, web scraping, and troubleshooting complex technical infrastructure.
