  • Crowdcast

    Crowdcast is an innovative suite for crowdsourcing with proximity-based interactions. Crowdcast is built on top of the Proximity framework, which efficiently connects you to your closest neighbors at all times, regardless of where you are and how far your closest neighbors are. In particular, Proximity addresses the Continuous All k-Nearest Neighbor (CAkNN) problem efficiently.

  • ooopa - Social Media Design and Development

    Help with the design and development of various pages of social media driven products ready for launch by Wadja Inc. in the US. I was working closely with the development team to provide support to their efforts to meet their launch deadline for 2 sites they were redesigning. Both services have a modern and simple focus, engineered for web and mobile interfaces.

  • Airplace

    A Platform for the Evaluation of Fingerprint Positioning Algorithms on Android Smartphones. The Airplace system is an end-to-end mobile positioning platform developed on Android smartphones that facilitates the construction of the radiomap and features real-time positioning, while offering the additional option to assess the performance of different fingerprint-based algorithms with respect to the positioning time, accuracy and power consumption.

  • SocialFace - Database Course Project

    Database system with a JAVA front-end for maintaining and querying social data about the users, coined SocialFace.

  • Find the Treasure - Graphics Course Project

    This game was developed as part of the graphics course. Navigating in an old traditional Cypriot mansion (Archontiko Ierodiakonou) using Microsoft's Kinect Sensor or Keyboard as the controller, the Greek character has to search and find items. We used motion capture technology in order to record the player's movements, like walking, collecting, running etc. All models (house, character, items) were edited in 3D Studio Max and other Autodesk products, like Motionbuilder and Maya. The game was developed using the XNA framework.

    You can download the game for free. Just send me an email...
