At Nara Network Japan, I design and test hardware, including FPGA firmware and software integration for the NNJ-SDR++ UHD Edition. I validated sustained 56 MS/s receive operation with real-time spectrum visualization and audio processing.
I also designed precision timing and phase-measurement instruments, including the TPLLV1/A and NNJ-PMS V1/A. Testing demonstrated stability in the 10⁻¹³ region for the TPLLV1/A and approximately 0.3–0.6 ps RMS short-term noise for the NNJ-PMS V1/A.
Earlier, I worked on network and systems engineering across data centers and telecommunications projects. For Lumen Technologies, I installed and monitored fiber and video-broadcasting equipment for the Tokyo 2021 Olympics.
