About me

Javascript is an incredible world of possibilities, and I am fascinated by that. I like to solve problems always trying to choose the best and more performative alternative, but sometimes we need to deliver, then, refactor! I enjoy working on small teams, I think we can make big things working with a few incredible minds. A few words can describe my skills:


  • JavaScript, Node.JS, Electron (S2), Ruby, Web API's, HTML5, CSS3, Groovy.
  • Experience as a team leader
  • Experience with remote teams (+6 years)
  • Great experience in web design, web development and graphic design.
  • Adaptive to new applications and technologies.
  • Always trying to learn a new crazy-last-week-mini-framework or creating new mini-ones

paste'n'Playlist!

Paste a list of songs with the pattern: Iron Maiden - Run to the hills (artist name - song title) and the tool will try to create a playlist with the Spotify tracks found. You can choose to add the results to an existing playlist or create a new one.

Semaphore Menubar

Semaphore Menubar is an Open Source Unofficial Semaphore CI Desktop App. At Follett, my team and I use semaphoreci.com to run our tests and we wanted to avoid keeping a chrome tab opened all the time to see if the build passed. So I created this Electron Application, a multi platform way to receive notifications of our builds using semaphore ci.
