Software Engineer · GenAI Platform Infrastructure

Hi, I’m Guadalupe.
I build agentic AI in production.

I work on the GenAI platform powering agentic systems for 10,000+ users at Wells Fargo — and ship LLM projects on the side: a fine-tuned race strategist, an AWS Bedrock shopping agent, and a RAG engine that surfaces contradictions instead of hiding them.
