Hi, my name is

Myung Guk Lee.

I bring hardware to life with code.

I am a Senior Firmware Engineer with over 15 years of experience, currently developing advanced 5G Radio Unit firmware at GreenWave Radios. I specialize in embedded systems architecture, real-time operating systems, and hardware-software integration for mission-critical applications.

Check out my work!

01. About Me

Hello! I'm Myung Guk,a firmware engineer passionate about building efficient, reliable embedded systems. My journey in embedded development began at Dasan Networks, where I developed software for networking devices.

Over the past 15+ years, I've worked across various domains from networking equipment to storage devices and wireless communication systems. This diverse experience has given me a comprehensive understanding of embedded systems architecture, real-time constraints, and hardware-software interfaces.

My approach combines deep technical expertise with practical implementation. I enjoy solving complex problems that bridge the gap between hardware capabilities and software requirements.

Here are some technologies I've been working with recently:

  • ARM Cortex-M/A/R
  • RTOS (ThreadX, FreeRTOS)
  • Embedded C/C++
  • Device Drivers
  • NEON SIMD
  • Tool Development using Python
