About this Gig
I am an experienced Embedded Systems Engineer with expertise in nRF52, ESP32, STM32, and real-world experience developing firmware for wearables, IoT devices, trackers, and smart sensors.
I can help bring your ideas to life by creating high-quality, production-ready firmware that integrates sensors, wireless communication, and low-power optimization.
My skills include:
- Microcontrollers: nRF52 series, ESP32, STM32, Quectel
- Communication Protocols: BLE, WiFi, MQTT, LoRaWAN, UWB, UART, I2C, SPI, QSPI
- Sensors & Modules: BMA400 (motion), STTS22H (temperature), PPG, audio detectors, beacons, Fall detection, Distance measurement
- RTOS & Frameworks: Zephyr, FreeRTOS, nRF Connect SDK, ESP-IDF, PlatformIO, STM32CubeIDE, IAR
- Firmware Features: DFU/FOTA, low-power modes, driver coding, mobile app integration
- UI & Display: LVGL, OLED, E-INK, SquareLine Studio
I provide complete source code, documentation and protcol for wireless communication. Each firmware is tested and optimized for real-world deployment.
Before ordering, please message me to discuss your project requirements so we can ensure the best solution.

FAQ
Do you offer OTA / DFU support for devices?
Yes, for Standard and Premium packages I can implement DFU/FOTA support, enabling you to update your device firmware remotely.
Which microcontrollers do you work with?
I specialize in nRF52 series, ESP32, STM32, and can also support Arduino, ESP8266, or custom boards upon request.
Do you provide documentation and support?
Yes. Standard and Premium packages include detailed documentation, wiring diagrams, and technical notes. I also provide support for 1–3 revisions depending on the package.
What if I need additional features after the project is delivered?
You can order custom extras or request a new project order. I can implement additional sensors, protocols, or optimizations as needed.
Can you work with my specific sensors or modules?
Absolutely! I have experience with a wide range of sensors and modules, including BMA400, STTS22H, PPG sensors, audio detectors, beacons, and more. Please provide your hardware details so I can confirm compatibility.
Do you provide source code with the firmware?
Yes! All packages include fully functional, well-commented source code. You will receive all files necessary to build, flash, and run your firmware.
