Hey! My name’s Jason, and I go by the handle enscribe/jktrn on pretty much every account. I do a lot of things to find fulfillment — I enjoy cybersecurity capture-the-flag competitions, rhythm games, beautiful READMEs, gluttony, web development and Tetris. You’ll mainly find CTF writeups around here, which I’ve poured lots of love into. Thanks for stopping by! (・ω・)ノ
