Informazioni su questo servizio
Struggling to get your hardware to perform reliably? I am a professional Embedded Systems Developer with a deep focus on creating robust, efficient, and scalable firmware. Whether you are prototyping on an ESP32 or moving to mass production with STM32 or PIC microcontrollers, I provide industry-standard code tailored to your hardware.
What I Offer:
- MCU Expertise: ESP32 (WiFi/BLE), STM32 (HAL/LL/Low Power), PIC (16F, 18F, 24F, 32MZ/MX).
- Specialized Bootloader Services: Custom USB, UART, CAN, Ethernet, and SD Card bootloaders (including EZBL modifications and Dual Bank updates).
- IoT & Cloud Integration: Secure connection to Firebase, AWS IoT, or MQTT brokers.
- Protocol Implementation: I2C, SPI, UART, CAN, RS485, and Ethernet.
- Peripheral Integration: Sensors, Displays, RTCs, and External Flash/EEPROM storage.
- Optimized Code: Efficient memory management (Linker files/Makefiles) and low-power optimization for battery-operated devices.
Why Choose Me?
- Clean & Documented Code: Written in C/C++ with maintainability in mind.
- End-to-End Support: From hardware abstraction to high-level application logic.
- Proven Track Record: Experience with complex memory mapping and custom linker scri

FAQ
I just need a bug fixed in my existing firmware. Can you help?
Yes, send me the code and describe the issue. Small fixes usually fall under the Basic package.
My MCU isn't ESP32 or STM32 — can you still help?
Probably yes. I've worked on PIC, AVR, NXP LPC2129. Message me first and I'll confirm
Will the code work on my actual hardware, not just an emulator?
Always. I write firmware for real hardware. I'll need your datasheet or schematic for hardware-specific work.
Can you add Wi-Fi OTA updates to my existing ESP32 project?
Yes — that's a Standard or Premium job depending on your current codebase. Message me with your code.
