About Julien

Full stack developer with 8+ years of experience, primarily in back-end, I design and develop end-to-end web applications.
After 3 years in startups (Matera, Padoa, Skello), I spent 5 years developing products in education and gamification solo — without commercial success. A demanding experience that made me highly autonomous on the entire stack and architectural choices.
My strong point: quickly mastering complex business logic. In startups, I worked on technical areas where functional rigor is paramount — condominium accounting, critical billing, historical data integration. These are the types of problems where I create the most value.
