    Please don't invite me if you need only some low pay (< $45/hr) low skills (such as ESP32, Arduino copy and paste alike etc) jobs, it's insulting for a professional, thanks. Thank you for taking the time to view my profile. I'm a professional electrical engineer with experience in power electronics, digital circuits, analog circuits, and HF RF circuits. My favorite EDA tools are OrCAD Capture CIS for schematics design, Allegro for PCB design, PSpice for circuit simulation, Verilog/Vivado for digital and FPGA design, SIMetrix/SIMPLIS for SMPS design. Still, I have used many other EDA tools under customer/client requests in the past, such as Altium Designer, LTspice, TINA-TI, ADS, Quartus Prime, etc. I'm also a professional programmer with experience in PC BIOS, BSP, Linux, and Android, and I'm familiar with many programming languages such as x86 assembly, ARM assembly, C, C++, Java, Python, HTML, CSS, XML, SQL, JavaScript, Unix shell script. I have many mass production designs for domestic clients and some from foreign countries. If you want reference to some of my product designs, I can ask for the client's permission as they are mostly NDA secured. I'm serious about the intellectual properties of others. But you can view my portfolio for a LF N2PK VNA and a Red Pitaya STEMlab125 designs, both are the few best in class amateur measurement equipment with professional device quality, I improved on their original design to better fit my daily electrical test requirements, and as I just produce my own improved design for my private use, so it's legal for me to show them here without IP issues with the copyright holders. My current interest and most recent skills are FPGA, SMPS, motor control, and automotive electronics. My previous strong skills are ARM architecture board design, BSP and Linux kernel porting, and Linux system programming.

    Senior mobile developer with experience of more than 6 years, familiar with native development under Android and iOS. Yet my skill sets are not limited to mobile development. In the last project I participated, I helped a startup company building their app(both Android and iOS) from scratch. Also I helped architect and develop all the backend services. Basically I know every corner of how to bring an idea into a real product. App development is a long process. Both clients and developers have to invest a large amount of time and energy. A failed project hurts deep for both sides. To guarantee the success of a project, I would evaluate client's requirements and expectations carefully before making any promise. Good communication is also crucial for freelance development; I am always available, feel free to contact and get problems solved.
