Hi there, I'm Mike

Embedded Systems Engineer | Building things that interact with the real world

I design and develop firmware for microcontrollers, build real-time operating systems, and create computer vision pipelines for autonomous robots.

Currently focused on STM32 + FreeRTOS ecosystem, exploring edge AI and IoT architectures.


STM32 FreeRTOS C Python Linux OpenCV
