Custom Firmware Development for ESP32 & STM32

I turn your ideas into smart, functional, and connected devices. Specializing in ESP32 and STM32 microcontrollers.

Do you have a hardware project that needs a software soul? Or an existing product to make "smart"? Firmware development is the heart of every modern electronic device. I write robust, efficient, and custom code to bring your products to life, from prototype to mass production.

My Firmware Development Services

I offer a comprehensive service to support you through every stage of the product lifecycle.

  • Custom Firmware Design and Development: Writing code from scratch, optimized for the specific needs of your hardware and features.
  • Rapid Prototyping: Developing Proof-of-Concept (PoC) and functional prototypes to quickly validate your idea in the field.
  • Connectivity and IoT: Implementing communication protocols for connected devices (Wi-Fi, Bluetooth/BLE, LoRa, MQTT, HTTP) to integrate your product with cloud platforms and mobile apps.
  • Resource Optimization: Developing low-power firmware for battery-operated devices and optimizing performance for critical applications.
  • Sensor and Actuator Integration: Managing any type of sensor (temperature, humidity, accelerometers, GPS, etc.) and controlling actuators (motors, relays, displays).
  • Board Support Package (BSP) and Drivers: Developing custom drivers for specific peripherals and components.
  • Debugging and Maintenance: Analyzing, fixing bugs, and updating existing firmware to improve stability and functionality.

Specialized Platforms

I have deep experience with the most versatile and powerful microcontrollers on the market.

STMicroelectronics STM32

For applications requiring high performance, reliability, and precise control of peripherals.

  • Advanced peripheral management (ADC, DAC, PWM, CAN, I2C, SPI).
  • Development based on the STM32CubeMX and HAL/LL ecosystem.
  • Implementation of Real-Time Operating Systems (RTOS) like FreeRTOS for complex, multitasking applications.

Espressif ESP32

The ideal choice for connected devices (IoT) and rapid prototypes thanks to its unbeatable cost/performance ratio and integrated connectivity.

  • Development of applications with Wi-Fi and Bluetooth (Classic & BLE).
  • Use of the native ESP-IDF framework for maximum control or the Arduino platform for faster development.
  • Creation of embedded web servers, MQTT clients, and REST API management.

My Approach

  1. Analysis: We start with your idea. Together, we analyze the functional requirements, technical challenges, and project goals.
  2. Design: I define the software architecture, choosing the most suitable components and technologies to ensure a scalable and maintainable result.
  3. Agile Development: I write clean, modular, and documented code. I keep you constantly updated on progress with incremental releases.
  4. Testing and Validation: I perform rigorous tests to ensure the firmware is stable, secure, and meets all required specifications.
  5. Delivery and Support: I deliver the complete source code and offer post-launch support for any integrations or future evolutions.
