firmware, software, embedded system, tech geek.

I am a senior software engineer specializing in low-level systems, including firmware development, embedded Linux, and FPGA/SoC prototyping. As a lifelong technology enthusiast, he enjoys exploring every layer of the software stack—from application-level tooling down to bare-metal firmware—always with an engineer’s focus on how systems really work. Beyond writing technical blogs, I also build hands-on projects ranging from C++ applications to FPGA-based SoC designs, which has shaped a practical, workflow-driven approach to learning and problem solving.
