I will debug, fix esp32 arduino stm32 firmware, embedded system

Is your ESP32, Arduino, STM32, or embedded project not working as expected?

I help diagnose and fix existing firmware and embedded-system problems without forcing you to rebuild the entire project.

I can troubleshoot:

• Compilation and library errors
• Firmware logic and unexpected behavior
• UART, I2C, SPI and CAN communication
• WiFi and BLE connectivity
• Sensor and module integration
• Timing, RTOS and task issues
• Watchdog resets, crashes and stability problems
• Memory and performance issues
• Incorrect sensor readings
• Hardware/software integration
• Code refactoring and optimization

My process is simple: understand the expected behavior, inspect the code and project structure, isolate the root cause, implement the appropriate fix, then explain what changed.

I can work with Arduino IDE, PlatformIO, ESP-IDF and STM32 development environments where applicable.

Send your existing firmware, schematic or wiring diagram, error messages, logs, or test results. The goal is a stable, understandable solution not a temporary patch.

Please message me before ordering with your MCU, hardware, code, current problem, and expected behavior so I can assess the scope and recommend the right package.
