Circuit, PCB and firmwarer engineer

I have good experience about schematic, PCB and programming.
I have worked more than 17 years on this part.

1) Schematic , PCB design and Prototypes
I have worked in PCB design of 2 ~ 38 layers with very high frequency for 4GHz and high speed RAM interface.
For embedded system and prototype development, I have rich experiences for industrial environment. I have completed many prototypes using PIC, STM32, ATMEGA, BLE, WIFI and so on.
Also, I have developed many embedded and power electronics devices.

2) Firmware Development Experiences.
I have rich knowledge and experiences at C/C++/Embedded C.
STM32 family, PIC16F/18F/33F, Atmega family, 8051 family, NRF51822/52832, MSP430, LPC, Atmel, CC2540/CC2541, CC3200, MPU6050, Wifi-MCUs : ESP8266/ESP32. Arduino: Arduino UNO, Arduino Mega2560, Linux-Embedded.

3)BLE, WIFI and Wireless Communication
nRF51822, NRF52832, DA14580, DA14583, Adafruit BLE, CC2540, CC1350 and XBee.
I like working on projects with a team.
