AI Engineer

Santiago Paz

RAG, agents and multi-agent systems.

Software engineer with 13 years building high-traffic web platforms, now moving into AI engineering. Taking LLMs into production means the retrieval, agents, guardrails and evaluation around the model, not just an API call. Throughout, a recurring thread of visual page builders that turn content models into systems non-engineers can drive.
