Big data analysis and development for improving openstreetmap.org (OSM) data.
Main contributor for the missing roads tool for OSM - http://improveosm.org
I was also in charge of the Hadoop cluster (1PB) administration/architecture.
Our input data consists of GPS probes from vehicles which we analyze with Spark and Machine
Learning (started out with MapReduce only). The results are elements which improve the map such as turn restrictions, missing roads and direction of flow.
My extra responsibilities are presented in the Managerial Skills section of this CV.
