About Fabien

A graduate with a Master's degree in MIAGE (Paris 1 Panthéon-Sorbonne), I have built my experience on a wide variety of projects: 3 years of work-study at Saint-Gobain on a platform used in 75 countries, a SaaS application in cybersecurity, a mobile app that I founded and managed from start to finish, and projects for smaller organizations like a hotel school.

What I enjoy about this profession is understanding the real need before writing a single line of code. I adapt to my interlocutor: whether you are a large company with well-established processes or a project owner looking for someone reliable to bring an idea to life.

I master the entire cycle: design, design (Figma), front and back development, testing, and production deployment. Angular, Java, NestJS, Docker, CI/CD… I am comfortable with the entire chain.

Naturally independent, I founded and developed MangaTracker alone, from the technical architecture to the AI recommendation engine. I also know how to quickly integrate into an existing team and adapt to its tools and methods.

If you are looking for someone serious, smiling, and truly invested in the success of your project, we should talk.
