Electrical engineer (Carabobo University, 2001) and backend developer, currently Software Engineer III at Asistensi Global Insurance. Two decades of Python across oil and gas, cloud and data engineering, business intelligence and insurtech.

Today most of my work is agentic AI: a multi-agent framework on LangGraph, an agentic terminal in Go, MCP servers, and Reflex components that bring React libraries to Python.
