About Me

Been in the business all my live

Hi — I'm Javier Loureiro Pérez, a software engineer and entrepreneur. I started my software career back in 2014 when I was 11, when I created a math blog for my fellow classmates to better explain the concepts we were learning and I started playing around with basic HTML.
