Senior Embedded Design Engineer
About this Gig
Need reliable firmware that actually works on real hardware? You're in the right place.
I'm a Senior Embedded Design Engineer with 4+ years building production firmware for IoT, defense, and smart consumer products including a patented BLE device (nRF52) now shipping in the market. Unlike code-only developers, I also design PCBs and personally test and debug hardware, so your firmware is delivered proven, not just compiled.
Platforms I work with: STM32 (incl. STM32WB) ESP32 / NINA / NORA nRF52 (Nordic) Arduino Raspberry Pi Nvidia Jetson Orin
What I can build for you: Sensor & peripheral drivers (I2C, I2S, SPI, UART, RS485, SDIO, ADC) Wireless connectivity: BLE, Bluetooth Classic, Wi-Fi, ESP-NOW Cloud & app integration: MQTT, Azure IoT Hub, JSON, REST Low-power and RTOS-based firmware Hardware testing, debugging & validation with full reports
Tools: STM32CubeIDE, Segger Embedded Studio, Arduino IDE, ESP-IDF, Raspberry Pi Imager, Linux
You get clean, documented, production-ready code plus clear communication and unlimited revisions until it works.
Message me before ordering so I can scope your project and recommend the right package. Also designing the board? Check my PCB design gig

FAQ
Which microcontrollers and platforms do you support?
STM32, ESP32/NINA/NORA, nRF52, Arduino, Raspberry Pi, and Nvidia Jetson. Message me with yours if it's not listed.
Do I get the source code?
Yes — full, commented source code plus documentation and a flashing/upload guide.
Can you also test and debug my hardware?
Yes. This is included in the Premium package. I test and debug with oscilloscope, function generator, multimeter, and power supply, and deliver a detailed test report.
Do you need my physical hardware?
For firmware-only work, no — I can develop and test on equivalent dev boards/modules. For full hardware bring-up, having the board helps; we can discuss options.
Can you design the PCB too?
Yes — I have a separate PCB design gig, and can deliver schematic + PCB + firmware as a complete package.
What do you need from me to start?
Your project requirements, target chip (if decided), datasheets/schematics if available, and any existing code.
