About

I build autonomous robots and robotics software with a focus on navigation, embedded systems, and real-world integration. I am a Robotics Software Engineer at Enchanted Tools in Paris, working on Mirokaï robots, and I am completing an MSc in Embedded Systems Engineering at ENSTA - Institut Polytechnique de Paris.

My personal and team projects explore vision-language models for social navigation, humanoid robotics, embedded systems, and autonomous competition robots.

Experience

Robotics Software Engineer

Enchanted Tools · Paris, France

Sep 2024 - Present

Develop and integrate robotics software for Mirokaï, with a focus on autonomous navigation, system integration, and validation on physical robots.

ROS 2 · C++ · Python · Linux

Test and Integration Technician Intern

Enchanted Tools · Paris, France

Apr 2024 - Jul 2024

Supported prototyping, testing, and integration for Mirokaï robots across hardware and software interfaces.

Selected Robotics Projects

VLM2Nav

Vision-Language Models for Social Robot Navigation

2026 - Present

Experimental ROS 2 stack exploring a local vision-language model as a high-level reasoning layer while conventional robotics remains responsible for motion. Temporal RGB observations become structured social decisions with freshness checks and hysteresis before semantic trajectory scoring and Nav2/MPPI execution. Qwen3-VL runs through vLLM on Jetson AGX Orin, with HuNavSim reactive pedestrians and a reproducible nine-scenario benchmark.

PHARE

Autonomous Humanoid Research and Experimentation Platform

2026 - Present

Co-Founder and Software & Embedded Systems Lead for a modular wheeled-biped humanoid research platform at ENSTA. The program covers ROS 2, embedded firmware and electronics, CAN architecture, state estimation, optimal control, reinforcement learning, simulation, and the transition from digital models to a physical robot.

RoboCup MSL

Robot Club Toulon · Goalkeeper Robot Lead

2022 - Present

I develop autonomous goalkeeper behaviors in C#, including stereo-camera 3D ball reconstruction, ballistic trajectory prediction, reactive positioning, and shot interception with a two-axis arm. The team finished world runner-up at RoboCup 2026 in Incheon, South Korea.

FIPATECH

French Robotics Cup · Founder, Team Leader & Software Lead

2024 - 2026

I founded and led the team around an autonomous holonomic robot built with ROS 2, Nav2, MPPI, multi-sensor localization, and online task planning. We took the system from simulation through integration and competition, finishing 17th out of 89 teams in the Senior category in 2026.

Open Source & Technical Projects

A selection of smaller public projects and contributions that show the software and systems work behind the larger robotics projects above.

Curated and maintained reference to the French robotics ecosystem, covering research, industry, open source, education, communities, and events with an emphasis on active and verifiable resources.

dslc - DSL to URDF Compiler

Python compiler tooling for robot descriptions

Built a small compiler pipeline with a lexer, parser, AST, semantic analysis, lowering passes, URDF generation and validation, automated tests, and a local Three.js viewer for mobile robot models.

audio_manager_ros2

Generic ROS 2 audio event server

Designed a reusable ROS 2 audio event service with priorities, layers, runtime modes, status reporting, control services, pluggable playback backends, and a null backend for simulation and CI.

PaxOS

C++ Contributor

Contributed upstream to the lightweight PaxoPhone operating system, including a merged message-management module and fixes to storage and translation unit tests.
