About

Behind Cauce is me: an International Business student and self-taught data analyst based in Colombia. I work at the intersection of trade, data and AI: I understand the business problem first, then build the technical solution.
My stack: Python, SQL, Excel and Power BI for data; AI-assisted development (Claude Code) to build and ship complete tools — pipelines, automated tests, CI/CD and production apps. I work in English and Spanish.
