Turn Your Data Into An Oracle.
By Eduardo Roldan & Luisa S. Avalos, PMP
Public AI tools don’t know your business. We build custom AI assistants, RAG systems, and grounded LLM workflows that answer questions from your data — securely deployed in your cloud, never used to train someone else’s model.

At ESR, we focus on LLM fine-tuning and RAG (Retrieval-Augmented Generation) to make AI work for your specific business data, ensuring responses are accurate, secure, and actionable.

LinkedIn“AI should be your most knowledgeable employee, not a random chatbot. We bridge the gap between public models and your private enterprise intelligence.”

LinkedIn“Generative AI is a behavior change as much as a tech change. I help your team agree on what's safe to use it for, train the people who'll use it daily, and document the new way of working.”
