Over deze dienst
Need firmware that works on real hardware, not just in a demo?
I'm an embedded firmware engineer with 4.5+ years of building products on STM32, ESP32 and nRF52840. I write clean, well-documented C that runs reliably in the field.
What I can build for you:
- STM32 firmware, bare-metal or FreeRTOS, with drivers for any sensor or peripheral
- ESP32 IoT devices with WiFi, MQTT, web dashboards and OTA updates
- nRF52840 BLE firmware on Zephyr or the nRF SDK
- LoRaWAN sensor nodes
- RS-485 and Modbus RTU communication
- Debugging and fixing existing firmware
Every order includes:
- Full source code, properly commented
- Build and flashing instructions
- Testing on real hardware
- A short handover note so you can maintain it
Please message me before ordering with your board, MCU and requirements, so I can confirm the scope and give you an accurate timeline.
Veelgestelde vragen
Do you work on custom boards?
Yes. Share the schematic, and either ship the board or I'll develop on the matching dev kit while you test on yours.
Which IDEs and frameworks do you use?
STM32CubeIDE, ESP-IDF, Arduino, nRF Connect SDK with Zephyr, VS Code and PlatformIO. I'll use whatever your project already runs on.
Can you fix firmware someone else wrote?
Yes. Send the project and a description of the problem, and I'll diagnose it before quoting.
Will I own the source code?
Yes. Full source code and rights are yours on delivery.
Do you offer support after delivery?
Yes. Bug fixes within the delivered scope are covered for 14 days.
