Hi, I'm Andres Vallarino 👋

Full-Stack Developer & AI Engineer · Buenos Aires, Argentina 🇦🇷

I build digital products with a focus on user experience, modern architectures, and the latest Artificial Intelligence practices. I specialize in React, but what truly sets me apart is the integration of multi-agent AI systems into real-world, production-ready applications.


🤖 Multi-Agent Architecture

I design and implement systems where multiple AI agents collaborate, delegate tasks, and correct each other autonomously..

🚀 Featured Projects

Tarot app with a built-in real multi-agent AI system. Interpretations are generated by 6 specialized agents that plan, execute, and self-correct using Groq API (Llama 3.3) in a Vercel Serverless Function.
