    ABOUT ME

    Been in the business all my life

    Hi, I'm Javier Loureiro Pérez, a software engineer and entrepreneur from Spain. 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.

    Data Structures & Algorithms

    I love problem solving and you may see me occasionally doing LeetCode on YT.
