About

My Background

I started my professional career as an avionics technician early on. But I've always had a passion for computers. At 14 years old I started learning C++. In high school I began reverse engineering and playing around with single player video games. As well as writing custom dll's to inject in games like AssaultCube to make use of its internal scripting system to make a menu to interact with my dll.

Nowadays

I've gotten further into reverse engineering. I used embedded RTTI to deduce the class hierarchy and interconnection of various classes within my favorite single player game: Deus Ex Human Revolution. I also used Wireshark's USB analyzer to reverse engineer an Xbox One Controller's USB communication protocol so I could grab input from the controller. I used that knowledge to make a device driver in Linux for it.

I've been learning more in-depth parts of Windows system internals as well as defense measures in binary exploitation. Such as ASLR, DEP, CFG and random XOR canary's.

Tools

My favorite disassembler is Ghidra and I like to use Frida to discern call stacks, function parameters and program behavior dynamically. I've messed around with angr and symbolic execution a little bit.

What I Have To Offer

Overall my passion and drive for all things computer and how they work on a deeper level makes me enthusiastic to work in reverse engineering.

Experience

My professional career has been almost exclusively in aviation. I was an avionics technician in the U.S. Air Force and was stationed at JBMDL (Joint Base McGuire-Dix-Lakehurst) in NJ.

From there I've worked for Comlux in Indianapolis, IN. A completion center for private and business class jets.

I went on to Gulfstream working on the newest models of their private jets such as the G650, G500 and G600.

After Gulfstream I worked for Tyonek at the Redstone Arsenal Testing Center. Working on a variety of helicopters.

My work as an avionics technician has taught me effective troubleshooting, how to read wiring diagrams, fundamental and intermediate electrical engineering concepts, a very deep understanding of complex systems such as autopilot and much more.

Education

I've always been self-taught when it comes to computer systems as well as what I learned as an avionics technician. I've been doing programming projects primarily in C/C++ as a hobby over the years. Reverse engineering has become a passion of mine however and is something I strive to learn more about every single day.
