Space Systems and Cybersecurity Engineer at Cromulence LLC
Melbourne, FL, United States
Details
Experience:
Building Hackasat CTF from the ground up since 2021. Quals challenges in orbital mechanics, space dynamics, satellite signal processing, quaternion pointing, and general spacemath madness. Evolving the finals architecture from hardware and over-the-air RF transmission to solar-system scale constellation simulation and RISC-V processor-level hardware emulation. Our infrastructure is played by the top CTF hacking teams in the world and we work hard to make sure they have fun and learn spacemath while they do it.
