    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.

    Mobile Apps -- Web Development

    United States - Last active: 1 day ago - Tests: 8 - Portfolio: 14

    I have a BA (with honors) from the University of Iowa (also double majored in Linguistics). I also have a Web Development Professional Certificate from Minneapolis Community and Technical College. I have been developing apps for the iOS platform since 2009. I have also worked on native Android apps, and I have worked on and created several cross-platform hybrid apps using Apache Cordova (or Phonegap) as well as custom hybrid solutions. I am resourceful and self-motivated when finding applicable solutions to programming problems (it's like a fun puzzle...). In the past I always focused on Apple platforms and was an expert on the now antiquated Macintosh Toolbox of the 1990's. I used C/C++ on these old generation Macs and on UNIX boxes while studying computer science (we also used early Java on the workstations). I still have a sweet spot for native objective-c development on iOS. Recent projects have included custom Cordova / Phonegap plugins, applications which make use of bluetooth iBeacons (as well as Gimbal BLE beacons), and in the last year I have worked extensively with Location Services including GPS functionality and Geofences. In the early days of iOS development I worked a lot with audio processing and muti-touch interactions. I never really set out with the intent to become a project manager, but I communicate well and it seems my role in many gigs recently tends to creep in that direction.
