Embedded Systems | STM32, nRF52, ESP32 | Real-Time Firmware, IoT & PCB

Embedded systems engineer and hardware designer with 10+ years turning product ideas into manufactured electronics, from schematic and multilayer PCB design in Altium to firmware on STM32, nRF52, ESP32, and FPGA/Zynq platforms. I build wireless and IoT products using BLE, LoRa, and Zigbee, and I've delivered hardware for industrial, automotive, medical, and aviation-grade applications, including ATEX/explosive-zone rated designs. I have taken two of my own product designs from prototype through to full production runs. One scaled to 1,000+ units and another to 100+ units, with me handling everything from board design to manufacturing coordination along the way. 𝗪𝗵𝗮𝘁 𝗜 𝗱𝗲𝗹𝗶𝘃𝗲𝗿 𝗲𝗻𝗱-𝘁𝗼-𝗲𝗻𝗱: System architecture and component selection, schematic and PCB layout/routing (up to 10 layers, mixed-signal and high-speed interfaces), prototyping and validation of boards with hundreds of SMD components, and embedded firmware/driver development in C/C++ and Verilog running on FreeRTOS, Zephyr, and other RTOS. I also support feasibility studies, cost estimation, and turnkey manufacturing coordination with PCB fabs, suppliers, and test labs, plus PCB reverse engineering and reviving obsolete hardware. 𝗠𝗖𝗨/𝗦𝗼𝗖 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲: STM32, Nordic nRF52/nRF9160, TI wireless MCUs, ESP32, Renesas, and Xilinx/Altera FPGA/CPLD/Zynq SoC. If you need a hardware or firmware partner who can take a project from concept through certified, manufacturable product, let's talk about what you're building.
