Hello, I am an expert in arduino/AVR/STM32/ESP8266/ESP32/ch32v003 and linux kernel device driver programming. I'm also an expert in C and modern C++(upto version C++20) programming on Linux. I've experience in developing complex projects on embedded devices which runs on million of devices(end-user products tv/mobile/EV charging stations). I've written my own IOT stack in C++/dbus, which interacts closely Home Assistant running on Raspberry Pi3 to control my smart devices at home. I can design PCBs too using Kicad ([login to view URL]) and also good knowledge of 3d modelling using FreeCAD. I've a ender3v3 se printer too. I've few patches in upstream linux kernel. Recent one is [login to view URL] I've also worked in bluez stack at linux side.
