About this Gig
Is your ESP32 or STM32 firmware not working as expected?
I can help identify bugs, troubleshoot communication issues, and fix existing embedded C firmware.
My services include:
- ESP32 and STM32 firmware debugging
- Embedded C code review and bug fixing
- UART, I2C, and SPI troubleshooting
- BLE and Wi-Fi connectivity issues
- MQTT communication and data-transfer problems
- Sensor integration and peripheral driver issues
- Firmware logic errors and unexpected behavior
What you will receive:
- Corrected source code for the agreed issue
- A clear explanation of the changes
- Troubleshooting findings and validation notes
- Support for the included revision period
I work with Arduino IDE, ESP-IDF and STM32 development environments and focus on practical, maintainable solutions.
Before ordering: Please share your code, error logs, development environment, and a clear description of the problem. Complex projects, multiple unrelated bugs, PCB design, and new firmware development may require a custom offer.
Let's get your embedded project working reliably!

FAQ
Which microcontrollers do you support?
I primarily work with ESP32 and STM32 microcontrollers. Please share your exact board and development environment before ordering.
Which programming languages and IDEs do you support?
I mainly work with embedded C using ESP-IDF, STM32 development tools and Arduino IDE. Support for other environments depends on the project.
Can you fix UART, I2C, and SPI issues?
Yes. I can investigate communication errors, configuration problems, peripheral drivers, and related firmware issues.
Can you debug BLE, Wi-Fi, or MQTT problems?
Yes, for supported ESP32 projects. Please provide logs, relevant code, and the expected versus actual behavior.
Do you need my complete project?
Not always. Please provide the smallest reproducible example possible, along with relevant configuration files, logs, and error messages.
Will you test the firmware on real hardware?
Physical testing depends on hardware access. I will clarify whether the agreed work includes code-level checks, simulated tests, or physical-device validation.
Can you develop new firmware instead of fixing bugs?
This Gig focuses on debugging existing firmware. New features or complete firmware development may require a separate custom offer.
What if my issue is more complex than the package?
Contact me with the project details before ordering. I can review the scope and propose a suitable custom offer if it fits my expertise.
