Senior PCB & Hardware Design Engineer
Fiverr • Freelance
May 2026 - Present • 2 mos
I provide end to end PCB and electronic hardware development for startups, inventors, manufacturers, and engineering teams. My work covers product architecture, component selection, schematic capture, multilayer PCB layout, circuit simulation, design verification, DFM, and complete manufacturing documentation. I have developed hardware for IoT devices, wearable biosensors, industrial controllers, audio electronics, battery powered products, smart devices, telemetry systems, and sensor platforms. My experience includes ESP32, STM32, nRF52, RP2040, USB-C, BLE, Wi-Fi, LoRa, Ethernet, LTE, CAN, RS485, I2C, SPI, and UART. I use KiCad, Altium Designer, EasyEDA, LTspice, and other professional engineering tools. Deliverables include editable source files, schematics, PCB layouts, Gerbers, drill files, BOM, CPL/Pick and Place files, assembly drawings, and 3D STEP models. Selected projects include compact wearable sensor boards, ESP32-S3 audio devices, Ethernet control systems, STM32 development boards, power management circuits, industrial automation controllers, and JLCPCB/PCBWay ready production designs.

Jan 2026 - Jun 2026 • 5 mos
I develop embedded hardware and firmware for connected products, industrial equipment, IoT devices, wearable electronics, audio systems, and battery powered products. My work includes microcontroller selection, embedded system architecture, peripheral integration, sensor interfacing, communication protocols, hardware bring up, debugging, firmware development, and prototype validation. I work with ESP32, STM32, nRF52, RP2040, PIC, and ATmega platforms using ESP-IDF, STM32CubeIDE, PlatformIO, Arduino IDE, Keil, FreeRTOS, and C/C++. I have implemented BLE, Wi-Fi, LoRa, Ethernet, USB, UART, SPI, I2C, CAN, RS485, I2S audio, SD card storage, display control, motor control, battery monitoring, and cloud-connected telemetry. Projects include BLE synchronized audio devices, wearable electrochemical sensing systems, Ethernet theater controllers, LTE telemetry boards, kiosk automation systems, smart-card development boards, and low power wireless sensor products. I also support PCB bring up, firmware troubleshooting, oscilloscope and logic analyzer testing, production testing, and coordination between hardware, firmware, and manufacturing requirements.
