What I've been up to lately?

Mexico City was home for about 20 years.

Have ample experience as a frontend developer on:

  • Creating apps from scratch
  • Laying out the guidelines for reusable and maintainable code
  • Implementing design systems
  • Fleshing out intuitive and performant UIs from provided designs
  • Help existing apps get up to speed with modern standards

Was awarded the Lázaro Cárdenas Prize in the Field of Engineering and Physical-Mathematical Sciences in 2005.

Worked with a variety of stacks and languages before settling down on Elixir for fullstack development with Phoenix, LiveView, and Tailwind CSS.

Can also do TypeScript / JavaScript along with Vue 3 and Tailwind CSS for frontend.

Continually learn new things. Right now looking into domotics and some of the new AI stuff.

Have worked as an employee, contractor, consultant, and mentor.
Try to write quality code using best practices. :monocle_face:

Hobbies range widely from Zen Buddhism to building PCs, writing blog posts and casual gaming. And every now and then I like to rewrite this blog in a new tech stack.
