Chi sono
Hi! I am a dedicated Computer Scientist and Full-Stack Developer with a passion for building and fixing complex systems. I specialize in two core areas:
🧠 AI & Custom LLMs: I build secure, custom RAG chatbots (Python, LangChain, vector databases) that let you interact with your private documents with zero AI hallucinations.
💻 Web App Bug Fixing: I quickly diagnose and resolve deep-rooted errors in React, Node.js, and MongoDB (MERN) applications.
I don't just patch symptoms; I fix root causes with clean, documented code. Let's build or fix your next project!
