Über diesen Service
Need firmware that is reliable, low-power, and actually ships? I'm a professional embedded engineer building production firmware for STM32, ESP32 / ESP32-S3, and nRF52 / nRF54 (Zephyr RTOS) devices from wearables and medical devices to industrial IoT.
What I deliver:
- Bare-metal and RTOS firmware in C/C++ (FreeRTOS, Zephyr)
- Peripheral drivers: I2C, SPI, UART, CAN, USB, I2S, RS-485
- BLE GATT/HID services, Wi-Fi, MQTT, and cloud sync
- Sensor integration (PPG, IMU, ADC) and on-device TinyML
- Low-power optimization, bootloaders / OTA, LVGL UI
- Board bring-up, debugging (J-Link / ST-Link), and clean documentation
You get commented source code, build instructions, and support to flash and run it on your hardware.
Every project is custom message me with your MCU, sensors, and goals for an accurate quote and timeline before ordering.

FAQ
What do I receive?
Commented source code, build/flash instructions, and documentation. Premium adds OTA and 30 days of support.
Do I need to send hardware?
No. I work from your schematic/board and can validate on dev kits; final testing is on your target.
Can you fix or optimize existing firmware?
Yes — send the repo and I'll quote a fix/refactor.
Why message first?
Firmware scope varies a lot; I'll confirm feasibility and send a custom offer so there are no surprises.
