À propos de Quentin

👋 Senior AI/ML & Full-Stack Engineer - Founder and former CTO

I help companies design, build, and deploy AI-powered products, from early prototypes to reliable production systems.

Over the past 12 years, I have delivered software as a technical founder, CTO, employee, and freelance engineer. My experience combines hands-on engineering, product strategy and team leadership.

My current focus is AI agents and applied machine learning, including:

- Agentic workflows and multi-step AI systems
- RAG pipelines, embeddings, retrieval, and evaluation
- Fine-tuning and custom model training, a lot of that was applied to finance and trading
- Classical and deep-learning models, including XGBoost and MLPs
- AI product architecture, APIs, infrastructure, and production deployment
- AI-assisted software development workflows

I also bring extensive experience as a senior full-stack engineer, particularly with React, Node.js, TypeScript, databases, cloud infrastructure, and distributed systems. This allows me to build the complete product around an AI system, not only the model or proof of concept.

Additional experience:

🌱 Raised €4M+ in seed funding as a founder
🎓 Engineering background from 42, complemented by business and product training at emlyon
👨🏼‍🏫 React and Node.js trainer for SNCF teams, and AI trainer for SMEs
🎨 Interactive 3D and WebGL development with Three.js
📍 Based in Paris and always happy to meet over coffee

Engagement model: I work on a daily-rate basis rather than fixed-price deliverables.

    Quantitative trading and Market Research
    janvier 2024 - Aujourd'hui (2 ans et 7 mois)
    I have a strong background in financial markets, combining experience as an equity analyst, CFA Level I training, and hands-on work on systematic trading strategies. I have researched and built short-horizon models for equities, FX, crypto, and prediction markets, using machine-learning approaches such as linear models, XGBoost, and neural networks. My work has covered data pipelines, signal evaluation, backtesting, execution costs, market microstructure, margin, and broker/exchange APIs, with particular attention to whether a statistical edge remains tradable after fees, spreads, slippage, and financing costs.

Quentin a rejoint une Scrum Team pour ajouter de nouvelles fonctionnalités à la web app. Il s'est très rapidement onboardé malgré la complexité de l'application et a joué un rôle moteur pour refondre le code selon les meilleures pratiques. L'équipe a apprécié le travail de Quentin tant d'un point de vue technique que relationnel, merci à toi !
