I work on embedded systems that need to function reliably outside the lab, especially ESP32 and STM32-based IoT devices using BLE, WiFi, and LoRa. I cover both firmware and PCB design, which avoids the typical back-and-forth between hardware and software that delays many projects. What I can help you with: - Turn your idea into a working embedded product (schematic → PCB → firmware) - Fix devices that crash, reset, or behave inconsistently in real use - Design production-ready PCBs with minimal rework - Resolve unreliable wireless communication (BLE, WiFi, LoRa, MQTT) - Optimize battery-powered devices for lower power consumption - Support transition from prototype to production Recent work: - Wireless trailer mover (Canada) - Broadcast tally light system (UK) - Wearable device firmware (USA) - Custom IoT and control systems How I work: - Direct debugging support (including remote sessions when needed) - Structured testing and design review before delivery - Clear communication during development - Post-delivery support to stabilize the system if required Technical stack: - Platforms: ESP32, STM32, nRF52, PIC, MSP430, Raspberry Pi, Nvidia Jetson - Firmware: C/C++, FreeRTOS, Zephyr - Hardware: PCB design (Altium, KiCad, EasyEDA) - Protocols: UART, SPI, I2C, CAN, USB - Wireless: BLE, WiFi, LoRa, MQTT If your system is stuck, unstable, or needs to move from idea to working product, I can help you move it forward.
