Our Data Story

With thousands of active lots every day, hundreds of thousands of daily bids, millions of users, and countless marketing campaigns, the Catawiki platform generates vast amount of data every day. This data is being collected and stored in the Data warehouse, which is used extensively by our team of 10 analysts and data scientists. There are also hundreds of active internal users of our Web interface to the Data warehouse.
As Catawiki grows and produces more data, our Analysts would like to perform even more sophisticated analyses, our Data Scientists want more data,  and yes, Product owners want more dashboards! With this in mind, Catawiki is building a new distributed data platform using tools from the Hadoop ecosystem that can accommodate the rapidly growing amount of data and requirements of analysts, data scientists, and product owners. 
We have started streaming event data and writing data pipelines in Apache Airflow that transform this data with Apache Spark, and now Catawiki needs more Data Engineers to help us tackle the challenge of bringing even more data sources into our platform and transforming and organizing this data for analysis and consumption by other applications. It’s a big challenge but one that we’re really excited about solving.
