I’ve always gotten bored fast. I can’t stand standing around, so I defaulted to coding. I’ve got a weird style, but it works — and I legit can’t sleep at night knowing my code’s gonna need a full rewrite in a few years. I build things to last, not to patch later; no hacks, no bandaids, just clean setups that hold up. Eventually I’ll be this generation’s Tony Stark — just gotta keep grinding.

I started GangDev because I’ve got a vision for how I want to impact the world, and I’m tired of being boxed in by outdated norms that slow everything down. I’ve set up cloud and physical servers from scratch, built web platforms completely from the ground up, and made game systems that scale forever without falling apart. I’m always trying to make stuff cleaner, faster, and smarter — one giga project at a time.

I'm not chasing clout, trying to boost my ego, or flaunt a fake persona; that's why I build things that are real. I want to be something my dad would be proud of — something 전설적인.
