Experience

  • Toggl Pomodoro Break Feature (Other amazing things)
    https://github.com/toggl/toggldesktop/pull/1951

    Toggl is a great tool to track time. They have their clients work publicly in an open source collaboration space where anyone can pull and improve and if lucky, get published on the platform for millions of users.

    They integrated a Pomodoro functionality last year, but there was no automatic Pomodoro break so I decided to implement it, and it was accepted and merged into the public stable version of the tool!

  • Google Apps Script for Calendar (Other amazing things)
    https://gist.github.com/unmultimedio/8cbacf4cae525b412278

    This code was a personal exercise that I made when I first encountered Google Apps script. There was a technology event running in Bogotá called Colombia 3.0 and at the time the agenda was being distributed to all participants via PDF or printed, which was not very useful if you wanted to attend the most-interesting-to-you talks.

    So I decided to move that information into a Google Sheet, convert those events to actual events in a Google Calendar, and make the calendar public to everyone, as well as the piece of code I wrote to make it work.

  • Static Landing Page (Other amazing things)
