    Engineer in Computer Science - Developer - Research

    France - Last active: 1 day ago - Tests: 15 - Portfolio: 1

    Hello, I am a 27 years old engineer in Computer Science from France. After graduating from the Institut National des Sciences Appliquées of Rennes, I moved over to Sweden to follow a master program on Mobile Systems. Meanwhile, I was also working as a freelance web-developer/project co-leader for a Canadian company. While learning, I participated as a trainee to many professional project and learn to be flexible both in my ways of working in a team and on the technologies to use. Indeed, even so my major programming languages are Java and PHP, I could easily learn C# during my master thesis in Sweden and build up a nice piece of software to work with Sifteo cubes. Software architecture and system design are two of my strong background points, thus I thrive in realizing project from the beginning until the end. My professional experiences involved many non programmer and non computer scientist customers and allowed me to train establishing their needs and to translate them into sprints, backlog and deadlines. I also believe that knowledge in computer science without knowledge of the real world are wasted hence my interests for books, sail, roller-skating, ice hockey as well as environmental questions for instance. Looking forward to working with you.
