I’m an Electronic Engineer. I have more than 5 years working in the electronic world as a developer. I have skills to solve both software and hardware tasks based on: arduino, rp2040, esp32, different PLC like Omron, stm32, FPGA. I prefer to design electronic boards in KiCad. I always make 3D models of future boards and advise clients on ordering these boards from manufacturers such as JLCPCB, PCBway. I can also develop a future board case using Solidworks. My main work is the development of control systems for elevators and various technological equipment, such as slicers for the bread industry, autoclaves, etc. So I can help with the invention of an electrical circuit diagram for controlling various mechanisms.
