Back to original languageAbout Valentin
Passionate about development, particularly Java and its ecosystem, I have implemented and honed my expertise over 9 years as a developer. My commitment and curiosity about the world of development, especially Java, quickly allowed me to become a technical reference for the latest Java features.
I can implement **complex systems around Java**, both by using my in-depth knowledge of Java and the various frameworks that revolve around it, and through different architectural solutions: DDD, TDD, Clean Code... All solutions that I adapt according to the needs and processes already in place within your company.
With anengagedandthoughtfulnature, I know how to integrate into teams and be **proactive**. Depending on the needs, I can take on the role of architect, lead developer, or developer.
