Built a data analytics app that accelerated Nielsen's seven-day ratings update into an overnight process
Nielsen needed to overhaul their outdated applications to meet modern demands. We transformed their flat-file data storage system into a modern, scalable, cloud-based data warehouse and built analytics apps for iOS and Android – accelerating their seven-day data update into an overnight process. This provided Nielsen – an historic business built on data —with modern technological agility to evolve with the future.
300Tb of data migrated to the cloud
14 disparate systems integrated into a single experience
Data update time decreased from weekly to daily
