À propos de ce service
I am an embedded firmware engineer with hands on experience building production grade firmware for ESP32, STM32, Arduino, PIC, AVR, and custom MCU based IoT devices. I write clean, tested, well documented embedded C and C++ code that runs reliably on real hardware not just in a simulator.
Whether you are starting from a blank chip or inheriting a half finished codebase that nobody wants to touch, I deliver firmware that works the first time it boots and keeps working in the field.
What I Build For You:
- ESP32 Firmware Development
- STM32 Firmware Development
- Arduino Firmware & Sketch Development
- FreeRTOS Embedded Application
- IoT Device Firmware
- BLE Firmware Development
- Sensor Driver Development
- UART / SPI / I2C / CAN Communication
- Modbus RTU & RS485 Firmware
- OTA Firmware Update Implementation
- Low Power & Battery Optimization
- Existing Firmware Bug Fix & Optimization
- Bootloader Development
- Display & UI Firmware
- Complete Firmware Documentation

FAQ
Can you work with my existing code or do you start from scratch?
Both. I can take over and fix existing firmware or write everything from scratch depending on what is faster and cleaner for your project.
Do you support ESP-IDF or only the Arduino framework?
Both. I use ESP-IDF for production grade projects where performance and low level control matter, and Arduino framework for rapid prototyping and simpler applications.
Can you connect my device to AWS IoT or a custom MQTT server?
Yes. MQTT over WiFi with TLS is included in the Standard and Premium packages connecting to AWS IoT Core, HiveMQ, Mosquitto, or any MQTT broker you use.
Do I get the full source code?
Yes, always. You receive the complete source code, project files, and build instructions no locked binaries, no hidden files.
My firmware works sometimes but crashes randomly can you fix it?
Yes. Random crashes are almost always a memory issue, race condition, or RTOS task priority conflict. Send me your code and I will find and fix it.
