I will develop embedded firmware for stm32, nrf52, ble, mqtt, AWS, and ota

Need help building or debugging firmware for a connected device? Im an embedded systems engineer with 7+ years of experience developing firmware and integrating hardware for sensor-driven, battery-powered, GNSS, and connected-device projects.

I can help with:

• Embedded C/C++ firmware for STM32 and nRF52840
• FreeRTOS-based development and peripheral integration
• BLE, sensor, and cellular modem integration
• MQTT communication and AWS-connected device workflows
• OTA update implementation
• Low-power optimization and battery-life improvements
• Board bring-up, firmware debugging, and hardware/protocol validation
• Python test scripts for repeatable hardware testing

My work has included reducing idle current from 30 mA to under 1 mA, developing Python test suites that reduced bring-up debug time by 30%, and building deployment tooling that cut customer site deployment time by 90%.

How it works:

Message me with your board or MCU, current firmware status, required features, and target outcome. Ill review the scope and send you a clear proposal before you place an order. For hardware-dependent work, well agree on what can be validated with the hardware and access available.
