AI and agents for businesses

I design and integrate artificial intelligence systems in your company: conversational and voice agents, assistants over corporate knowledge, intelligent document processing and agents that operate with your systems.

What I implement

Conversational and voice agents, assistants that answer from your company’s internal knowledge, intelligent document processing and agents that consult and update your systems.

Process first

Not every task needs AI. Before proposing a solution I analyse the process and the available data, and define which part AI takes on and which part a person should review.

Data, permissions and validation

I define which information the system uses, who has access and which provider processes the data. I validate the answers with real cases, including those with no answer, so the system recognises when the information is not available.

Technology

OpenAI, LangChain, LangGraph, ElevenLabs and Python, deployed on AWS or Azure depending on the project.
