Embedded system developer | Circuit/PCB design | MCU/FPGA/DSP | C/C++ | STM32/ESP32 | IoT | GSM/GPRS | GPS/GLONASS/BeiDou
I have a great deal of experienced in:
Schematic / HDI multilayer PCB design
MCU/FPGA programming
IoT technologies
ESD requirements
3D modeling
Product prototyping, preparing for fabrication
Power supply design
C# Desktop connectivity firmware
I will:
- Design electrical schematics for your concept or technical task
- Choose electronic parts
- Design PCB layout
- Write firmware for MCU/SoC/FPGA/DSP/PC
- Design device 3D layout
- Assemble a device and test it
- Prepare full documentation for manufacturing and mass production
- Propose my ideas on how to improve your project and make it more profitable
- Offer further solution support
I have more than 13 years of professional embedded and electronic systems design experience. I also have good communication skills and can easily understand client ideas. I am ready to discuss your requirements and communicate with you and your team via audio and video chat. In addition, I can help you create technical and business requirements for your project if you don't fully understand which features you want.
It is important for me to build long-term relationships with clients, so I am primarily looking for long-term projects.
If you have an ideas or questions then I would be happy to give you an answer. Just let me know and I will help you.
