About

Schematic , PCB design,Prototypes and firmware.

I'm working with hardware and software engineer for 15 years.
I have good experience about schematic, PCB, prototype and firmware.

1) Schematic , PCB design and Prototypes
I have worked in PCB design of 2 ~ 38 layers and very high frequency for 4GHz and to 20000 pins.
And I can convert pcb projects between Altum, Egale, Allegro, Protel, PADS.
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/CC26xx, 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, XBee and ZWave 700, Smartthings.

I like working on projects with a team that cares about creating beautiful and usable interfaces. It's important to me to build long term relationships with clients, so I'm primarily looking for long term projects. I'm flexible with my working hours and am happy to work closely with any existing freelancers you work with. I look forward to hearing from you!
