Jax Dunfee ctfs

I primarily play the categories of pwn & web

I've been writing CTF challenges for awhile now mainly in the web and pwn categories, though I do occasionally make challenges in other categories.

Please note that some of my challenges are private as they were made for work, I've attempted to consolidate those that are public here. I greatly enjoy creating challenges that help others learn and grow, and I hope you enjoy them too.
