I’m a PCB Design and Embedded Hardware Engineer with around 7 years of experience designing reliable, production-ready electronics for prototypes, startups, and commercial products. I specialize in taking projects from concept and schematic through PCB layout, prototyping, debugging, and manufacturing. I work with Altium Designer, KiCad, and EasyEDA, and can deliver complete manufacturing packages including Gerbers, BOM, Pick & Place files, assembly drawings, and 3D models. My experience includes: • 2–6 layer PCB design and layout • ESP32, STM32, Arduino, nRF52 and other MCU-based designs • Power supplies, battery and charging circuits • Sensor and analog interfaces • USB, UART, I2C, SPI, CAN, RS485 and other communication interfaces • RF and wireless designs including Wi-Fi, Bluetooth and LoRa • Connectors, displays, LEDs, buttons, relays and motor interfaces • DFM/DFT and manufacturing optimization • JLCPCB/LCSC-ready designs and component selection • PCB prototyping, bring-up, debugging and hardware revisions • Mechanical integration, enclosure design and PCB-to-enclosure fit I don’t just focus on routing traces. I look at the complete hardware system, including component availability, electrical reliability, manufacturability, mechanical constraints, and how the finished PCB will actually be assembled and used. Whether you already have a validated schematic that needs professional PCB layout or need help developing the electronics from the ground up, I can help turn your idea into a working, manufacturable product. If you have an existing schematic, PCB, or project files, send them over and I can review the current design and discuss the next steps.
