Since I love to talk and hear others talk about computer science and programming, I've been (as attendee or organizer) to many conferences, user groups, university classes and meetups, and spoke in some of them about my experiences and opinions. I usually work in Java, recently started doing some Kotlin, and had the luck of writing some Scala in the past. A few months per year a bunch of students call me "professor". I am happy the most when my work makes others work less and better.
