I’ve been self-taught since I was a kid, and I’m currently studying InfoSec in Hong Kong. My interests span red teaming, reverse engineering, web development, web hacking, and app development — mostly software hacking stuff. I started taking things seriously around middle school, beginning with HTML, CSS, and JavaScript, then moving through C#, VB.NET, and a few others. Most of those are behind me now; these days I focus on web hacking and red team work.

I'm a huge GNU/Linux enthusiast. I've tried at least 20 different distros and experiments over the years. My main system is Arch Linux — seven years and counting. Yes, I'm still a student with over seven years of experience; I started back in secondary school. Right now I'm using my own Arch-based distribution called UmmItOS, named after my internet nickname. XD

I used to be a Windows user, but I'm now 100% on GNU/Linux. I only touch Windows when I'm attacking Active Directory. Lots of stories from the journey ... this is just a small part :D
