AI Tools Specialist · Bilingual EN/ES

Building
intelligent
systems.

I'm a software development student with a focus on AI engineering. I build real tools — chatbots, RAG pipelines, and autonomous agents — with a bias toward shipping things that actually work. Bilingual EN/ES, based in California.
