Dr. Clemens Gröpl

Working in the "Media Measurement" department on the refinement of passive observation data collected from the digital devices (mobile, laptop, router) of persons participating in market research studies. - Reconstructing behavior by aggregating raw observation data from browser plugins, mobile apps, VPN tunnels, etc. - Rule-based annotation. - Daily ETL processes. - In-depth data analysis. - Handling incidents. - Implementing algorithms in SQL or Spark/Java. - Docker, Gradle, Atlassian, GitLab, Airflow.

Worked in the department "Semantic Web Project" on a prototype of a novel internet search engine. - Design and implementation of algorithms for analysis of the link structure of large web graphs. - Created a data processing pipeline for various ranking factors in web graphs of more than 10 billion links. Java code was based on Hadoop and Hypertable.

Worked in the "Navigation Engine and Services" department on the core component calculating the routes inside the navigation devices. - Efficient and versatile access to digital map data - Introduced data access layer to support both TomTom's proprietary and Navigation Data Standard (NDS) format. - Implement geometric search queries. - Introduce CMake build system, supporting Android and Windows builds in addition to Linux.
