About Me

Senior Computer Science student at UTRGV with real-world experience building AI-powered applications, interactive data visualizations, and research tools. I work at the intersection of Python development and applied AI — using tools like the OpenAI API and LangChain to build things that actually solve problems.

Bilingual English/Spanish. TEDx speaker. Currently open to entry-level roles in AI engineering, data analysis, and Python development.
