Coding came to me at an early age, I've always been interested in electronics and programming. Starting out by making very bad "games" in GMS2, to now wanting to strive further and learn more and truly learn and become a 'full-stack' developer.
To me a full-stack developer isn't one that just knows React and Express.js, but somebody that can dig down to the hardware level and understand what happens from the electrical signals on the PCB up to what's displayed in a browser.
