Nicolas N.

I help hardware and IoT product companies develop stable, secure, and production-ready firmware for ESP32, STM32, nRF, and other microcontroller-based devices.

With 10+ years of hands-on embedded software experience, I’ve worked on commercial products used in international markets - from low-level drivers and device bring-up to connectivity, OTA updates, RTOS architecture, security-related implementation, debugging, and long-term firmware maintenance.

What I can help with:

- Firmware development for ESP32, STM32, nRF, and other microcontroller-based platforms

- Embedded C/C++ and Python tools for development, testing, and automation

- IoT connectivity: BLE, Wi-Fi, Ethernet, MQTT, HTTP/HTTPS, WebSocket, Modbus

- RTOS-based architecture with FreeRTOS

- Peripheral integration: UART, SPI, I2C, RS485, CAN, USB

- OTA updates, bootloaders, firmware protection, and secure update flows

- Security-related firmware implementation: encryption, TLS/SSL, secure communication, authentication, and firmware integrity checks

- Embedded UI and display work: TouchGFX, LVGL, TFT/LCD

- EN 18031 cybersecurity compliance for RED: requirements analysis, secure firmware implementation, evidence preparation, and technical documentation

- Debugging production issues: crashes, memory leaks, watchdog resets, connectivity problems

- Hardware bring-up and hardware-software integration

- Long-term support, refactoring, stabilization, and product improvements

I’m especially useful for companies that need not just code, but a reliable firmware partner who can understand the product, identify weak points, and bring embedded systems to a stable production level.

Feel free to reach out if you need help with IoT, firmware, or embedded systems projects.
