I work as a PCB Design and Embedded Systems Engineer, providing end-to-end electronic hardware and firmware development for prototypes, product concepts, and custom electronics projects. My work covers the complete process from circuit concepts and schematics through PCB layout, design verification, manufacturing documentation, and embedded firmware. I specialize in custom PCB design, schematic capture, circuit design, component selection, footprint creation, PCB routing, single/double/multilayer boards, PCB redesign, modification, and reverse engineering. I also design application-specific boards including Arduino-based PCBs, ESP32 hardware, LED PCBs, high-power LED and aluminum MCPCB designs, flexible PCB, FPC, and rigid-flex solutions. I help clients move from breadboard and prototype stages to professional PCB designs, including converting breadboard and Fritzing prototypes into structured schematics and manufacturing-ready PCB layouts. I also work with embedded platforms such as Arduino, ESP32, and ESP8266 for hardware integration and firmware development. My firmware services include microcontroller programming, ESP32 firmware development, Arduino programming, IoT functionality, Wi-Fi/Bluetooth integration, and legitimate Bruce Firmware configuration or customization where applicable. Tools & Technologies: KiCad, Altium Designer, EasyEDA, Autodesk Eagle, Arduino IDE, ESP32, ESP8266, Arduino, electronic sensors, communication interfaces, and embedded systems. Typical Deliverables: schematic source files, PCB source files, Gerber files, NC drill files, BOM, Pick & Place files, PDF documentation, 3D PCB views/renders, firmware source files, and manufacturing-ready design packages. My focus is on clean engineering practices, accurate component placement and routing, design-rule verification, manufacturability, organized documentation, and clear communication throughout each project.
