Agentic AI Architect & Leader.
I’m Felix Reyes. I connect agent architecture, enterprise data, and business needs to turn AI into repeatable, useful work. My hands-on experience spans Copilot Studio, Microsoft Fabric, reusable skills, and automation.
I’m the author of ANSI SQL for FP&A Analysts and The Skills Pack, published in 2026. This is a home for those books, the projects that go with them, and whatever comes next.
