Languages: Flex, PHP, SQL, C++, C#, Java, Matlab, Python, OpenGL

Selected Projects: • Co-clustering/Market Segmentation of customers/products for IBM • Rotation Invariant Matching of Shapes and Images • VoIP Matching System for System S • Implementation of a system for storage and fast retrieval of similar multidimensional object trajectories. The system can retrieve trajectories that are similar to the user's queries and is designed to be robust to noise. Example data for the system include GPS data, or sign language recognition data. • Design and implementation of multithreaded distributed file system. Access and control of local & remote files and directories. • Application for code optimization for the low-level code written in language C--. • Application for code optimization for DLX CPU. • Program for discovery of frequent transactions using the "Apriori" algorithm. • System implementation for luminance and geometry corrections of images captured by an infra-red camera, for the assembly of infrared reflectogram mosaics (Bachelor Thesis, Aristotle University of Thessaloniki).
