Education

  1. 2013 — 2015

    M.Sc. Geographic Information Science

    University of Twente — Faculty ITCEnschede, NL

    Cum laudeGPA 8.6 / 10
    Thesis

    Real-time spatial indexing for streaming location data

    Designed a hybrid geohash and R-tree index that kept nearest-neighbour queries under 5ms on a stream of 50k positions per second. Parts of it ended up in a production fleet system.
