Abdurrahman M.

I help startups, businesses, and individuals turn electronic product ideas into professionally designed, manufacturing-ready PCBs. I'm a PCB Designer and Embedded Hardware Engineer specializing in schematic design, multilayer PCB layout, and embedded systems development. I work with STM32, ESP32, SAMD21, and ATmega microcontrollers, along with analog and digital circuits, power electronics, and RF hardware. Services I provide: PCB Design: Schematic capture, component selection, and multilayer PCB layout using KiCad and Altium Designer. Embedded Hardware: Custom STM32, ESP32, and ARM-based hardware, sensor integration, communication interfaces, and IoT devices. Power & Analog Electronics: Power supply design, voltage regulation, signal conditioning, and analog circuit development. PCB Manufacturing: Gerber files, BOMs, pick-and-place files, and complete JLCPCB/PCBWay manufacturing documentation. Hardware Review & Debugging: Schematic reviews, PCB design verification, troubleshooting, and prototype improvements. 3D & Mechanical Integration: PCB 3D models and custom enclosure design using Fusion 360. I focus on practical engineering, not just producing design files. My goal is to deliver reliable, cost-effective hardware that's easy to manufacture and designed with real-world performance in mind. Whether you need an existing PCB improved, a complex circuit designed, or a completely new electronic product developed, I can help bring your project from concept to a manufacturing-ready design.
