Junseok Kim

I am a Cellular Protocol Firmware Engineer at Samsung Electronics, developing 5G NR/LTE modem firmware. My work focuses on wireless protocols, modem performance optimization, and HW/SW co-design.

I bridge the gap between protocol design and embedded implementation. I have optimized throughput, voice quality, power efficiency, and CPU workload for the Galaxy and Pixel series. I address cross-layer challenges to maximize modem performance and stability.

I earned my Ph.D. in Electrical and Computer Engineering from Seoul National University, specializing in wireless networks and PHY/MAC modeling. I approach engineering from first principles, balancing algorithmic design with hardware constraints.
