A site about things

I make and break software. An avid systems programmer with an emphasis on Unix philosophy & reverse engineer. Checkout my blog where I write about my projects mostly, also checkout my journal where I share various thoughts and opinions about things. Artwork above by @hsgrace!

Some projects I’m proud of:

OpenFusion: FusionFall Server Emulator, relevant post
Laika: RAT written in modern C
Cosmo: Embedded scripting language, inspired by Lua
LuaDecompy: Lua 5.1 bytecode decompiler for Python

Checkout my resume here.

Any questions or concerns can be emailed to me at openpunk@protonmail.com. I also have an RSS feed if you’d like to keep tabs on me :)
