I’m a game developer who enjoys digging into all kinds of tech, with a side interest in finance and investing.
This blog is my little corner for organizing what I learn — programming notes, the bugs I run into, hands-on tutorials, and the occasional post on finance or a passing thought. Writing things down gives me notes I can revisit later, and now and then one of them might be just what you were looking for.
Feel free to browse the posts below — I hope you find something useful here.
