Sebastian López

AI Engineer

I build AI agents and LLM-powered tools.

I like to build AI-powered tools, using RAG, voice agents, and agentic frameworks, to help NGOs, cooperatives, and small associations. These tools let them automate workflows, access localized knowledge, or interact with technology by voice. My goal is to scale the moment when someone realizes a long-standing problem is suddenly solvable.
