I will design schematic and pcb for your iot project

I am Zahid Hussain, a PCB and embedded systems engineer specializing in custom multilayer PCB design (28 layers) for IoT and industrial electronics, covering schematic design, component selection, high-speed routing, controlled impedance, EMI/EMC mitigation, and power integrity. I develop embedded firmware in C/C++ for ESP32, STM32, PIC, Arduino, and Jetson, integrating industrial protocols (RS485, Modbus, CAN) and IoT stacks (MQTT, ThingsBoard, AWS). My expertise includes power supply design from 12V to 440V, motor control, sensor interfacing, and mixed-signal systems, with a strong focus on DFM/DFA, cost optimization, and manufacturing readiness. I deliver production-ready hardware, complete Gerbers, BOM, pick-and-place, test documentation, and perform systematic debugging, failure analysis, and design validation to ensure reliability from prototype to mass production.
