About
A bit about me

I'm a Software Engineer from Mexico City with 15+ years in the industry and a deep interest in design, UX, AI, and performance. I run a small studio called Bliss DDM.
I've helped teams at American Express, BBVA, Natura, Turing, and TrueCar ship at scale, and built custom software for startups including Rivian, Hiatus, and Zenfolio.
I take on engineering work where craft, performance, and a clear product story actually matter. Most of my output is private. Some of it lives in open source. I also speak at meetups, mostly about UX, TypeScript, and accessibility.
My wife and I have two kids , 11 dogs , 2 parakeets , 2 bunnies , and an unreasonable number of plants .
