Available to hire
Apple Technologist since 2005 from Germany. Worked for the Volkswagen Group and have led iOS initiatives at many companies. I love exploring new hardware (Vision Pro, Apple Watch) and sharing knowledge through talks and hands-on workshops.
Beyond coding, I teach iOS development (Apple Foundation Program), mentor teams, and author books and tutorials on privacy and Apple technologies. I enjoy helping teams design scalable architectures, package reusable Swift libraries, and speak at conferences around the world. Languages I speak include French, English, German, Spanish and more; I bring a collaborative, friendly approach to every project.
