Embedded systems engineer in training, passionate about the intersection of hardware and software. I design and program microcontroller-based systems — from bare-metal C/C++ firmware to real-time operating systems — with a strong background in electronics, signal processing, and RF communications. Currently in my second year at CESI Toulouse, seeking an apprenticeship to deepen my expertise in firmware development, PCB design, and real-time embedded applications.

Architecture of microcontrollers (ARM Cortex-M, AVR), bare-metal C/C++ firmware development, peripheral drivers (I²C, SPI, UART, GPIO, timers), interrupt handling, and DMA transfers. Applied object-oriented programming in C++ for hardware abstraction layers. Studied real-time operating system concepts (task scheduling, semaphores, queues) and embedded network protocols.
Analog circuit design: op-amp amplification, active filtering (Butterworth, Chebyshev), power regulation. Radio frequency: modulation schemes, antenna fundamentals, signal chain design. Automatic control: PID tuning, Bode/Nyquist analysis, stability of linear systems. All validated with LTSpice simulations and bench measurements (oscilloscope, signal generator, multimeter).
Developed a short-range radar prototype aimed at future autonomous car applications. Designed the RF signal chain including antenna selection, transmitter/receiver circuitry, and signal modulation (FMCW). Implemented signal processing algorithms in Python to extract distance and relative speed from the radar returns. Validated the system with bench measurements and real-world obstacle detection tests.
Designed and built a complete audio amplification chain from scratch, from preamplification to the final power stage driving a custom speaker enclosure. Selected and dimensioned op-amp stages, active crossover filters (Butterworth), and a Class AB power amplifier. Measured frequency response, THD, and gain using an oscilloscope and signal generator. The finished speaker was fully functional and characterised on the bench.
Built a fully autonomous weather station on an STM32 microcontroller. Integrated temperature, humidity (DHT22), pressure (BMP280), and UV index sensors over I²C and single-wire protocols. Developed bare-metal C firmware including sensor drivers, data averaging, and a low-power sleep mode between acquisitions. Data was displayed on a small OLED screen and transmitted wirelessly over a serial link for logging on a PC.
Toulouse, April – June 2026. Developed a complete graphical user interface for the aerospace simulation software CSIPI (Python/PyQt or Java). Created data visualisation modules and post-processing tools for simulation outputs. Collaborated closely with ONERA researchers and end users in an aerospace R&D environment.
Design, management, and exploitation of relational databases with MySQL. Engineering projects in the construction sector: structural design on Revit, strength of materials calculations, and technical project management with Fusion 360.
Limoges, July 2021. Observation internship focused on 3D modelling and animation. Required rigor, patience, and precision. Time management and deadline adherence. Experience in individual and collective projects.
Intensive daily training (18h/week), national championship participation. Managing the dual project of academic success alongside high-level sport demands. Stress management, perseverance under pressure, continuous performance improvement.
