I will do stm32, esp32 and arduino programming and firmware development

I work on embedded firmware development, debugging, peripheral integration, communication protocols, IoT connectivity, RTOS-based applications and hardware-software integration. I can support both new development and existing STM32, ESP32 and Arduino projects.

Yes. A large part of my R&D work involves existing products where firmware needs debugging, optimization, new features, protocol integration or hardware changes. You can send me your existing source code, schematic and project requirements for review.

Yes. Debugging is a major part of embedded R&D work. I can investigate issues related to peripherals, interrupts, timing, communication, sensors, memory, FreeRTOS tasks, hardware interaction, and firmware logic. The required time depends on the complexity of the existing system.

For STM32 firmware development, I mainly work with STM32CubeIDE, STM32 HAL/LL, Embedded C/C++, and FreeRTOS when required. For ESP32 programming, I can work with ESP-IDF and the Arduino framework depending on the existing project and technical requirements.

Yes. I regularly work with UART/USART, I2C, SPI, CAN, RS485, Modbus, ADC, PWM, timers, interrupts, DMA, WiFi, BLE, MQTT, and different sensors, displays, and communication modules.

Yes. I can work with custom STM32 and ESP32 hardware. If you are using a custom PCB, please provide the schematic, MCU part number, relevant datasheets, pin configuration, and any existing firmware so I can properly understand the hardware before development.

have 6+ years of hands-on R&D experience in embedded firmware/software development and have worked with 20+ startups, helping develop and ship embedded products. My experience includes firmware development, debugging, hardware integration, communication protocols, and product-level embedded systems.
