Electronic device designer
Thanks for your time to view my profile.
I'm a professional electronics engineer with experience in power electronics, digital circuit, analog circuit and HF RF circuit, my favorite EDA tools is OrCAD Capture CIS for schematics design, Allegro for PCB design, PSpice for circuit simulation, but I use ADS for some RF circuit design job too, and I use Eagle for some simpler and not performance critical circuit design also.
I'm also a professional programmer with experience on PC BIOS, bootloader, Linux and Android, and I'm familiar with a lot programming Languages such as x86 assembly, ARM assembly, C, C++, Java, Python, HTML, CSS, XML, SQL, JavaScript, Unix shell script.
I have a lot mass production designs for clients from China and some from foreign countries, if you want reference to some of my product design I can ask for permission of the client as they are mostly NDA secured and I'm serious to intellectual properties of others and I don't want to disclose the secrets of others too.
But you can view my portfolio for a LF N2PK VNA design which is copyrighted to myself so I can share it publicly for your reference, and if you are interested I can even send you the design files for review.
My current interest and most recent skills are SMPS design, motor control and automotive electronics, my previous strong skills are ARM architecture board design, BSP and Linux kernel porting and Linux system programming.
