Experience

  • Spontaneous Coders (Development)
    https://github.com/DeadalusVIII/spontaneous-xna-library

    This is a project portfolio website that I shared with some colleague engineers, which lists several of our creations. This includes code libraries, development tools, plug-ins, utilities, and more. The scope and purpose of each project have been diverse: to answer an academic assignment, a friend request, a personal need, or for any other spontaneous reason.

  • Imagine City (Development)
    https://www.youtube.com/watch?v=B8Ge3nN_NiI

    A 3D business simulation game, designed to be a massive multiplayer online game integrated with social networks.

    The objective is to build a city from scratch and try to address the many problems that arise from it (hunger, unemployment, pollution, and more). In short, the idea is to try to reach the 8-millennium goals at this small scale and to try to realize the difficulties of it as well as to learn how to accomplish them. This is done by constructing and evolving roads and buildings, passing laws and measures, and establishing partnerships with other players. Each of these actions can contribute in many different ways to improve your score regarding the millennium goals’ achievement.

    Imagine City is intended to be a never-ending game—the player’s objective is to improve his city as much as possible and compete in the world’s Imagine City Ranking.

    This project was developed using .NET C# and XNA Framework technologies; all in the scope of Microsoft's Imagine Cup 2010 competition.

  • Tag Tournament (Development)
    http://tagtournament.pabsilva.com/

    This is a 2D game, designed for two players. The game story is based on a love triangle, between two protagonist school students who are rivals: Tom and Jon who are both competing for a girl's affections.

    They do so by drawing graffiti hearts with their own names and the girl's name as well, aka tagging, in as many spots as possible while trying to survive the many obstacles and foes (instigated by each other) in a school environment.

  • Gemini (Development)
    http://arxiv.org/ftp/arxiv/papers/1302/1302.3862.pdf

    This is a middleware framework that maps body poses or voice commands to actions in any game. This not only warrants a more natural and customized user-experience but it also defines an interoperable virtual controller.

    Body poses and voice commands are respectively recognized through the Kinect's built-in cameras and microphones. The acquired data is then translated into the native interaction scheme in real-time using a lightweight method based on spatial restrictions. The system is also prepared to use Nintendo's Wiimote as an auxiliary and unobtrusive gamepad for physically or verbally impractical commands. This framework also provides a game-controlling tool that is totally customizable and very flexible—thus expanding the market of game consumers.

    The framework was developed in C# and was cited in a scientific publication.
