Jingtao Z.

I am a professional embedded software engineer with more than 10 years of experience. My current areas of expertise are IoT Applications & Embedded Systems Design, including embedded hardware/software. My Skills: - Know about MCU: Nordic, Silicon Labs, AVR, PIC,ESP32, etc. - Have experience in programming languages such as C/C++, - Solid knowledge of standard interfaces such as I2C, SPI, UART, and CAN. - Have experience using debugging tools such as Segger Jlink, CAN bus analyzer, Logic analyzer,RF analyzer. - IoT devices with wireless connectivity such as LTE, CAT-M1, NB-IoT, BLE, WIFI, NFC - Good experience in Battery Management Systems based on BQ products from TI. - Have experience using Alitium designer,Kicad - Know about medical Regulations and Directives such as EN 300 328,RoHS & REACH，EN 62368-1，EN 55032, EN 55035 etc. The development platform : - Keil .stm32cube, Micochip studio - On semiconductor IDE, Simplicity studio, - esp32-idf, Arduino - nrf connect sdk What I can do for you: (1 ) Electronic components selection,Schematic , PCBA design, output production files (2) Help you to review schematic , pcb files, and test hardware (3) quickly assist in making pcba samples, functional verification and abnormal problem analysis (4) Embedded software development from 0 to 1. (5) Help you to add new function or module to your embedded software system (6) Help you to review code ,test , fix bug in softeware (7) Based on the prototype of your needs, convert it into an actual embedded system design My advantage: （1） The processing and manufacturing efficiency in China is very high, and the cost of components is very low. If you want to do circuit modification and verification, I can use China's JLC and Taobao to quickly make PCBA. （2）I'm a full-stack developer capable of tackling both software and hardware challenges. This allows me to consider software design feasibility and convenience from a hardware design perspective, and vice versa.
