I’m Mário and I build systems for the web.
Here you’ll mostly see me writing about Software Development. Occasionally I also write about other topics that interest me, which includes Snowboarding, Longboarding and House Dance.
I have public office hours for those that would like to talk about software development or career advice.
I also run indexfundinvestor.eu where I help European residents learn about passive/index investing.
