That was the entry point \u2014 not a class, not a curriculum. A server that had to stay up, players who noticed within seconds when it did not, and no one to escalate to.<\/p><p>Everything followed from there. PHP and databases because the community site needed one. Linux because that is what the box ran. Network and security because the box got attacked. I learned the stack in the order the problems arrived, which is a slower start and a much more durable foundation than learning it in the order a syllabus presents it.<\/p><p>The scope kept growing and the pattern kept repeating: something breaks, nobody knows why, I go find out. Web development turned into application development. Application development turned into database administration, because the queries were the bottleneck. That turned into systems and infrastructure work, because the database was only as good as the machine underneath it. Interfaces between systems became a specialty almost by accident \u2014 they are where things break, and where nobody wants to look.<\/p><p>Somewhere in there I formalised it.
