Hello. I am an expert for Embedded System Design. To design the hardware (circuit design and PCB layout) and develop the firmware is my main skill.
I already have experience doing many designs with Altium, kicad, allegro in my company. You can see your PCB in 3D(CAD).
I also have developed the firmware(ethernet, usb, oled, WIFI, BLE... ) for many projects with STM32, PIC32 and ESP32. I wish you will contact me and discuss.
Thanks.
