Three crafts, one toolbox

I am a French computer science student at EPITECH and a visiting Computer Science student at Tsinghua University. I work across data science, machine learning, LLM agents, full-stack development, real-time collaborative systems, and game development. My recent work includes Hytale mods used by a large community, a collaborative browser-based game creation platform, and AI systems for geospatial and insurance-data use cases.

AI & Data Science

Built ML and agentic systems with PyTorch, Azure ML, LangChain, LangGraph, geospatial APIs, and SAS/Python data pipelines.

Web & Systems Engineering

Developed full-stack products with React, TypeScript, NestJS, Prisma, PostgreSQL, Docker, WebRTC, Yjs, S3/CDN infrastructure, and generated API clients.

Game Development & Modding

Created Hytale systems, custom weapons, persistent maps, party mechanics, Godot jam games, C++ engines, raytracers, and collaborative browser-based game tooling.
