πŸ§‘β€πŸ’» About Me

I'm a Distinguished Technical Architect on Data and AI at Salesforce with deep roots in data β€” from wrangling raw datasets to deploying ML models in production. I hold an M.S. in Data Science from Northwestern University and an M.S. in Data Engineering from WGU and bring a rare combination of technical depth and customer-facing consultative experience across the data and AI space.

Before tech, I served in the U.S. Military, which shaped my approach to problem solving: methodical, high-stakes, and mission-first. I'm fluent in English and Spanish, based in Miami, FL, and equally at home in a Jupyter notebook and a customer discovery call.

🧭 What I Build

The recurring shape across most of my work β€” agentic, conversation-first UIs talking to enterprise data through MCP. Click any node to jump to a representative repo.
