About Jerome

From the depths of the ocean to space, I design embedded systems that cannot afford to fail.

With over 20 years of experience in the most demanding environments (Aeronautics, Defense, Space, Rail, IoT), I support industrial companies and innovative startups in the success of their hardware and software projects.

My value proposition:
I don't just write code, I secure and make your products reliable.
From global architecture to board design, through real-time firmware and automated tests (CI/CD), I intervene from A to Z.
Whether it's to unblock a critical project ("firefighter" mission) or design an architecture from scratch, I bring a systemic "Hardware + Software" vision to deliver robust, optimized, and maintainable products.

My Technical Stack:

Languages: C, C++, Python, Assembly
OS & Architecture: RTOS (FreeRTOS, Zephyr, RTEMS, ucOS II), Embedded Linux, Bare-metal
Targets: Microcontrollers (STM32, ESP32, TI, ATmega), DSP (C6x, C54), FPGA
Buses & Protocols: Aero/Military (ARINC 429, AFDX, PCIe) & Industrial/IoT (CAN, MQTT, BLE, WiFi, I2C, SPI)
Hardware: Analog/Digital design, Orcad, VHDL

My Track Record:

Aeronautics & Defense (Thales...): Multi-bus test architecture, secure communication systems, observation on Rafale.

IoT & Greentech: End-to-end design (HW/SW) of a connected solar heating system that achieved 83% energy savings.

Functional Safety: Development of critical firmware for opening Parisian metro doors.

Do you have an IoT product to launch, a communication system to secure, or a critical architecture to make reliable? Send me a message to discuss the technical challenges of your project.
