I am a PCB Design Engineer specializing in schematic design, PCB layout, and hardware debugging for real-world electronics systems. I can help you with: • Custom PCB design (KiCad / EasyEDA) • Schematic design from idea or rough concept • PCB layout (2-layer / 4-layer / 6-layer boards) • Circuit debugging and optimization • Component selection and BOM creation • ESP32 / Arduino / microcontroller-based system design I have hands-on experience building: • Wireless communication systems (LoRa, RF) • Sensor-based embedded systems • Battery-powered and low-power devices • Motor control systems with fail-safe mechanisms I focus on designing reliable, manufacturable, and cost-effective PCBs — not just visually clean layouts. I have also developed multiple patented systems in embedded and autonomous technologies, which reflects my approach to solving problems at a system level, not just at circuit level. If you need a working product, not just design files, I can help turn your idea into a reliable hardware solution.
