About Julien

After initial training in computer vision and image processing, my professional journey naturally led me to Android development. All my experiences have involved creating mobile applications, which has allowed me to master the subtleties of Android development and acquire sharp expertise in Kotlin.

For over 3 years, I have been working daily with Kotlin and am now passionate about Kotlin and Compose Multiplatform, technologies that are redefining the cross-platform development experience.

Whether for native or cross-platform projects, I am always curious to take on new challenges and explore opportunities for technological innovation. Do not hesitate to contact me to discuss your projects or potential collaborations!
