  6. Late 2013

    Fundamentals at W3Schools

    HTML (learned)CSS (learned)PHP (learned)MySQL (learned)

    After HSC ended I went deep on w3schools.com. I didn't really understand the languages yet, but I learned enough to use them and build working websites. Deep understanding came later.

    C (learned)Java (learned)JavaScript (learned)PHP (learned)SQL (learned)MySQL (learned)REST APIs (learned)Android Apps (learned)Unity 3D Basics (learned)Computer Science Fundamentals (learned)

    Daffodil International University. Where most of the foundation came from. The self-taught years made the core concepts click fast. Built 20+ mobile apps, two rewarded by the university. At this stage I built real world web applications and developed some games, the exact things I was dreaming about back in 2007-2009.

  8. 2016–2020
