Modernised Data Architecture Based on BigQuery for a Real Estate Platform
An efficient data management architecture capable of collecting and processing large volumes of data from multiple sources. The solution deals with a complex data architecture involving numerous tables. The data architecture has not been changed for several years, so the Leobit team had to deal with a complex system, completely restructure the data integration flows, and provide an innovative architecture devoid of performance bottlenecks, limited capacities, and poor organization, peculiar to its predecessor.
Our team showcased great speed and efficiency in improving the customer’s data management architecture. In three weeks, we provided the client with a modernized architecture allowing them to make data collection more performant and scalable, as well as preparing it for gradual updates that wouldn't trigger the entire process.
