I am a professional PCB design and electronics engineer specializing in schematic design, PCB layout, and hardware prototyping. I use tools such as Altium Designer, KiCad, EasyEDA, and Proteus to deliver industry-standard circuit designs. My expertise includes ESP32, Arduino, Raspberry Pi, power electronics, motor drivers, and high-speed PCB layout with signal integrity analysis. I also provide simulation using Multisim, LTspice, and MATLAB/Simulink. From concept to production (JLCPCB, PCBWay), I ensure accurate footprints, clean layouts, and manufacturable designs....
