About this Gig
Here is a highly professional, icon-free version that is shortened to under 1,100 characters so it easily fits within Fiverr's limit while keeping your important C/C++ keywords.
Professional C and C++ Firmware Engineering Services
Welcome. If you need production-grade, highly optimized C and C++ firmware for your embedded systems, I am here to help. I specialize in writing clean, reliable, bare-metal and RTOS firmware designed for commercial and industrial-grade hardware. By avoiding hobbyist wrappers, I ensure your system operates with a minimal memory footprint, maximum speed, and rock-solid stability.
Microcontrollers and Toolchains Supported
- STM32 Series: Development via STM32CubeIDE utilizing HAL, LL libraries, or bare-metal C.
- ESP32 and ESP8266: Native ESP-IDF framework development, utilizing FreeRTOS and dual-core optimization.
- Nordic Semiconductor: Development via nRF Connect SDK and Zephyr RTOS for low-energy systems.
Firmware and Driver Capabilities
- Hardware Protocols: Expert integration of SPI, I2C, UART, CAN Bus, RS485, and Modbus.
- Custom Driver Coding: Development for IMUs, GPS, specialized sensors, flash storage, and displays.
- Power Optimization: Low-power architectur

FAQ
What development environments and toolchains do you use?
I work natively with industry-standard toolchains. For STM32, I use STM32CubeIDE with HAL or LL libraries. For ESP32, I write pure C/C++ using the native ESP-IDF framework. For Nordic Semi, I use the nRF Connect SDK alongside Zephyr RTOS.
Do you provide the complete source code, and who owns it?
Yes, the complete, well-commented C/C++ source code is included with every delivery. Upon completion and acceptance of the project, full ownership and intellectual property rights of the code belong entirely to you.
Can you implement multitasking and real-time operating systems?
Absolutely. I specialize in multi-threaded firmware design using FreeRTOS and Zephyr RTOS. I can efficiently manage task synchronization, queues, semaphores, and Mutexes to handle complex, real-time operations securely.
What information do you need before starting my project?
Please provide your hardware schematics, data sheets for any specialized sensors or peripherals, and a clear functional description of how the firmware should behave. Sharing these details upfront ensures an accurate timeline and quote.
