Description

🤷‍♂️ Who am I?

An engineer with a dual degree from Epitech (Master's in Computer Science) and the University of Kent (MSc Artificial Intelligence), I focus on two complementary areas: software development in TypeScript and AI engineering in Python. This duality allows me to design products where the application layer and the intelligent layer are conceived together — without friction between two providers with different specifications.

✍️ What I bring

- Fullstack web & mobile development — front and back (TypeScript)

- Integration of AI & LLM models into production (Python)

- Data processing & computer vision pipelines

- Robust API development & cloud deployment

- Rapid prototyping of AI features (RAG, vision, multi-modal)

⚙️ Main Technologies

- Web & Mobile: TypeScript, React, Next.js, React Native, Node.js, NestJS, Tailwind CSS

- AI & Data: Python, PyTorch, LangChain, OpenCV, YOLOv8, Scikit-Learn

🚀 Additional Information

I engage in missions where technology serves a clear product objective. Whether it's building an API, integrating an ML model into an existing app, or going from zero to an intelligent MVP — I adapt to the scope and context of your team. Feel free to contact me to discuss.

Valentin is a very promising profile that I recommend for Fullstack missions, particularly around React/NextJS/Tailwind CSS. Always very available, good-humored, and with good communication, he doesn't give up in the face of difficulties. He has met technical challenges and will quickly become an excellent experienced developer.
