I've been intern at Decathlon's Quechua for about 6 months in 2014. Those are a sample of the projects I've worked on. Confidentiality doesn't allow me to say much but the first project is an application using the altimeter and the barometer of the Quechua Smartphone. The second one is a smartwatch project. The last one is a security project.
