Hello! I am an experienced electrical engineer and PCB designer with over 10 years of expertise in developing innovative, reliable, and high-quality electronic solutions across diverse industries. Holding a bachelor’s degree in electrical engineering, I have a proven track record of designing, developing, and deploying advanced circuits, embedded systems, and IoT devices. What I Bring to Your Project: • PCB Design & Layout: Skilled in schematic capture and PCB layout using Altium Designer, Cadence, PADS Mentor Graphics, KiCad, EasyEDA, and RapidHarness. I have extensive experience designing multi-layer (up to 24 layers), high-density, HDI PCBs suitable for medium and high-volume production. I am familiar with manufacturing processes including JLCPCB for PCB fabrication and local support within China to facilitate manufacturing, prototype assembly, and quick revisions. I am committed to providing results on time and maintaining clear, prompt communication with clients. • Microcontroller & Firmware Development: Proficient in programming STM32, ESP32, PIC, AVR, STM8, and STC microcontrollers using Keil, STM32CubeIDE, VSCODE, MPLAB X IDE, and more. I excel in developing firmware for IoT, automation, and embedded systems. • IoT & Wireless Communication: Expertise integrating Bluetooth, BLE, LoRa, NB-IoT, RFID, WiFi (4G), MQTT, and other protocols into embedded systems. • Sensor & Display Systems: Development of color screens, segment displays, touch panels, and interface solutions for user-friendly product experiences. • Communication Protocols: Extensive experience with I2C, SPI, UART, CAN, RS232/485, Modelbus RTU, IR, RF (433/315 MHz, 2.4G, 4G, LoRa). • Reverse Engineering & Troubleshooting: Capable of analyzing, debugging, and optimizing complex circuits. • Power & Multimedia Systems: Power management circuits, LED lighting, audio devices, sensors, and multimedia integration. • Support for China Local Manufacturing(PCBWAY, JLCPCB): In addition to design, I offer local support within China to facilitate manufacturing, prototype assembly, and quick revisions. This ensures smooth collaboration and shorter lead times Why Work With Me: I am passionate about delivering precise, innovative, and reliable designs tailored to your specific needs. I prioritize quality, efficiency, and clear communication to ensure your project’s success — from prototype to production. I am committed to providing results on time and responding promptly to any client inquiries, ensuring smooth and efficient collaboration.
