About

Hi, I’m Tyler Vu — an embedded software engineer based in Hà Nội, Vietnam.

I work primarily on ARM Cortex-M microcontrollers, real-time operating systems (FreeRTOS, Zephyr), and the unglamorous-but-critical layer between hardware and application code. This blog is where I keep notes from things I learn along the way.
