About

I'm a Backend & AI Engineer from Mexico with 4+ years designing and building REST APIs, microservices, and intelligent pipelines. I specialize in NestJS, Python, and FastAPI — and I care deeply about clean code, developer experience, and shipping things that actually work.

Currently working at Rotoplas as a Fullstack Engineer, and contributing to a year-long project at Google.
