PCB Design Engineer | Multi-Layer Layouts | ESP32 & STM32 Expert

Stop wasting time on boards that don't work. I design manufacturing ready, multi-layer PCBs that bring your electronic products to life. I am a professional Embedded Systems Engineer specializing in high quality schematic capture and PCB layout. Whether you need a simple 2-layer prototype or a complex multi-layer industrial board, I ensure your design is optimized for both performance and Design for Manufacturing (DFM) to keep production costs low. Core Expertise: ✅PCB Layout: High-speed digital, precision analog, and power electronics (Multi-layer). ✅Hardware Integration: Extensive experience with ESP32, STM32, Arduino, and LoRa. ✅Schematic Design: Component selection, circuit simulation, and custom library management. ✅Manufacturing Files: Full production packages (Gerber X2, BOM, Pick-and-Place, 3D STEP). ✅Industry Tools: Expert proficiency in KiCad, Altium Designer, and Autodesk Eagle. Why work with me? ✅ Manufacturing Ready: I don't just "draw" boards; I design them to be built according to IPC standards. ✅ Fast Turnaround: Clear communication and strict adherence to your project deadlines. ✅ Post-Delivery Support: I provide technical support until your board is successfully fabricated and assembled. Let’s discuss your project requirements. Send me a message or click "Invite to Job," and I’ll provide a quick initial review of your concept!
