Informazioni su questo servizio
Need production-grade, highly reliable firmware for your STM32 microcontroller? You are in the right place.
I am an Embedded Systems Engineer with 6+ years of experience designing robust firmware architectures for industrial IoT, automotive, and commercial products. I specialize in maximizing the power of ARM Cortex-M cores using industry-standard development frameworks.
### Technical Expertise & Capabilities:
* Operating Systems: FreeRTOS, Zephyr RTOS, and Bare-Metal architectures.
* Peripherals & Bus Protocols: Hardware implementation of SPI, I2C, UART/USART, CAN Bus, RS485, and Modbus.
* Advanced Drivers: DMA (Direct Memory Access), Timer configurations, ADC/DAC calibration, and custom Bootloaders.
* Memory Management: Internal/External Flash layout optimization, EEPROM emulation, and power-fail safety.
* Power Optimization: Low-power configurations, sleep/standby modes, and battery management for field devices.
### Toolchains & Ecosystems:
* STM32CubeIDE / STM32CubeMX
* Keil uVision / IAR Embedded Workbench
* HAL (Hardware Abstraction Layer) & LL (Low-Layer) drivers
### Why Choose Me?
* Corporate-Grade Code: Clean, modular, thoroughly documented, strictly structured code.

FAQ
Do I need to provide hardware, or can you design everything from scratch?
I can design everything from scratch — schematic, PCB layout, and firmware. Just describe your project requirements and I'll handle the rest. If you already have hardware, I can write firmware for your existing board.
What software do you use for PCB design?
I primarily use KiCad (open-source, free for you to edit) and Altium Designer. I can deliver files in either format, plus standard Gerber/Excellon files compatible with JLCPCB, PCBWay, OSHPark, and all major fab houses.
Can you integrate with AWS IoT, Google Cloud, or Azure?
Yes. I have experience connecting ESP32 devices to AWS IoT Core (MQTT + TLS certificates), Google Cloud IoT, Azure IoT Hub, and simpler platforms like Thingspeak, Blynk, and Home Assistant.
Do you support LoRa and long-range wireless protocols?
Yes — I work with LoRa (SX1276/SX1278 modules), LoRaWAN (The Things Network / Chirpstack), Zigbee, and Z-Wave. Great for agricultural sensors, smart meters, or any application requiring kilometer-range connectivity.
What if I need the device to run on battery for months?
Power optimization is a specialty. I implement deep-sleep cycles, wake-on-interrupt routines, and efficient sensor polling schedules to achieve months-long battery life on a single 18650 cell. I'll also design the battery charging and protection circuit if needed.
Will you sign an NDA?
Absolutely. I respect IP confidentiality and am happy to sign a Non-Disclosure Agreement before you share sensitive project details. Your idea stays yours.
Can you help if my project is partly done but has bugs?
Yes — debugging and code review are offered as standalone services. Share your existing code and schematic and I'll identify issues, fix bugs, and optimize performance. This is available under the Basic or Standard package.
