Hi, I'm Josiah Keller. I'm a software developer and reverse-engineer. I'm an alumnus of the computer science department at Taylor University.

I got my start writing macros in Microsoft Excel. Then I moved on to full-stack web development. Now I spend most of my time in Ghidra looking at ARM or 68000 disassembly.

Currently, I'm at Peraton Labs, working on several embedded systems projects.

You can find me on Twitter, GitHub, LinkedIn, and Stack Overflow.

If you want to contact me, send an email to josiahbkeller AT gmail.com.
