Software Engineer

AnyPlace: Indoor Positioning and Navigation System for Big Data

  • Developed a complete architecture for an Indoor Positioning and Navigation system that provides a Web2.0 API for 3rd-party clients backed by Couchbase, a NoSQL datastore. (

  • Implemented an Android app that offers real-time positioning and navigation indoors, and a web-based application developed using Google Dart that provides similar services through any HTML-5 compliant browser.

  • Designed & implemented a Wi-Fi RSS-based radio map construction algorithm that can filter out useless Access Points and erroneous or unnecessary Wi-Fi fingerprints using Hadoop (Map-Reduce framework).

University of Cyprus (Research labs)

Software Developer, Intern


  • Developed a plugin for Eclipse IDE to provide content assistance and custom pre-processing for an in-house language.

  • Processed and presented crowd movement simulation data in a realistic 3D stage using 3D figures - Unity3D, KINECT


University of Oxford

Oxford, UK

  • Master of Science in Computer Science, Grade: Distinction

  • Thesis: Single-round vs Multi-round Distributed Query Processing in Factorised Databases

    • Designed and implemented a distributed join query evaluation engine (C++), coined D-FDB. In contrary to traditional systems, D-FDB uses data factorizations (f-representations) end-to-end exploiting their theoritical size-bounds against flat relational tables minimizing the total query execution time.

    • Developed serialization and bit-compression techniques to efficiently transmit data factorizations over the network whilst retaining the factorization compression levels.
