CodeFoxSoft Java Portfolio

Long before AI could write code, and before Stack Overflow had all the answers, I was teaching myself to speak the machine's language. My journey didn't start with a bootcamp; it started in the dark with QBasic and a help file, grinding out logic one syntax error at a time. I graduated to Java armed only with the raw API documentation and a text editor, building physics engines and cryptographic tools from scratch. This repository isn't just a collection of files; it is the fossil record of that evolution. It is proof that I didn't just download my skills—I forged them in the trenches of manual coding. This foundation is why, today, I don't ask AI for help; I give it orders.
