Interests


My Duolingo Profile

I enjoy Japanese culture and have been teaching myself the language for a few years now. Above is a image link to my profile on Duolingo! I am also an avid nerd and enjoy hobbies such as Dungeons and Dragons, Trading card games such as Magic the Gathering, and tabletop wargames such as Warhammer 40k. I love 3d printing and have many machines in both resin and FDM style. I have a fair bit of experience using these to create miniatures and terrain for the previously mentioned games.


My HackTheBox Profile

In my free time I also engage in CTF platforms and ethical hacking challenges and competitions. My favorite of these is Hack the Box which I use frequently. I have a personal goal to complete all of the boxes on the platform, which is no small feat to be sure. Above is a link to my HTB profile so you can track my progress!
