Jeri developed various hardware and software modifications for the Commodore 64 DTV, greatly expanding its functionality beyond its original design. This included adding features such as keyboard support and cartridge ports.

As co-founder of Technical Illusions, Jeri was instrumental in the design and development of the castAR augmented reality glasses. This innovative device projected holographic images onto a retroreflective surface, creating a unique augmented reality experience.

During her time at Valve, Jeri developed and demonstrated a method of creating a fully functional replica of the classic MOS 6502 microprocessor (used in the Commodore 64), using nothing but discrete components (transistors, resistors, capacitors). The feat was documented in a series of YouTube videos, and displayed her engineering skills.

Jeri is the inventor behind the core technology of Tilt Five, the augmented reality gaming system that projects holographic images onto a physical game board. This involved designing both the hardware (glasses and game board) and the software that powers the holographic experience.
