Desarrollador frontend e ingeniero
馃挕 Frontend developer and engineer 馃殌 Building products that make developers happy


I have loved creating things since I can remember. That is why, a few months after graduating as an engineer in Telecommunications and Electronics, I learned to code.

Today, I am a frontend developer at Datamart, a Chilean fintech company, and in my free time I create tools and content that make life easier for developers.

I have experience troubleshooting through web applications and browser extensions using technologies such as HTML, CSS, Javascript, TypeScript, Next.js, React, Plasmo, Astro, Tailwind and Boostrap.

Don't forget to follow me. I hope all my work is useful to you.


Currently I am building the following projects:


  • HTML
  • CSS
  • JavaScript
  • TypeScript
  • Next.js
  • React
  • Plasmo
  • Astro
  • Tailwind
  • Bootstrap
