Defense · Client: Undisclosed Prime Contractor
Developed custom on-the-spot RF signal generation scripts that emulated communications systems and signals-of-interest during a week-long exercise. This software enabled a prime contractor to demonstrate real-world capabilities using live data rather than simulated data.
Intelligence & National Security · Client: Undisclosed Cybersecurity Practices
Advised multiple cybersecurity practices on selecting and integrating hardware and software options to construct dedicated RF exploitation laboratories.
Electronics
Provided design feedback for a custom printed circuit board developed for a short-range IoT system, identifying low-cost RF integrated circuits and optimization of their board layouts.
