Need reliable embedded firmware written by an engineer who has deployed it in real industrial and automotive systems?
I'm Amir, an Embedded Firmware Engineer with 5+ years writing production C/C++ code for Arduino, STM32, and ESP32 platforms. My firmware runs in automotive ECUs, industrial control boards, and IoT devices — in real conditions, 24/7.
WHAT I CODE:
✔ Arduino firmware (C/C++) — sensors, actuators, displays, communication
✔ STM32 firmware using STM32 HAL and LL libraries (F1, F2, F3, F4 series)
✔ FreeRTOS real-time applications — tasks, queues, semaphores, timers
✔ Motor control — stepper motors, DC motors, encoder feedback, closed-loop control
✔ Sensor integration — ADC, temperature, pressure, encoders, IMUs, load cells
✔ Communication protocols — CAN bus, I²C, SPI, UART, RS-422, Modbus
✔ Automotive firmware — ignition timing, fuel injection, throttle control, O₂ sensor reading
✔ Python scripts for Raspberry Pi — data acquisition, logging, processing
PROVEN REAL-WORLD RESULTS:
→ STM32 firmware for 3 standalone automotive ECUs — zero failures over 3+ years in vehicles
→ FreeRTOS firmware for 10+ industrial boards running 24/7 for 4+ years
→ Encoder calibration and real-time position feedback for precision stone-scanning machines
→ 50% boost in system speed through firmware and interrupt optimization
→ CAN bus communication stack built and validated under automotive EMI conditions
WHAT YOU RECEIVE:
→ Clean, well-commented source code (C/C++ or Arduino .ino)
→ Full project files — ready to compile and flash
→ Brief documentation explaining the code structure
→ Post-delivery support for integration questions
