Data Sharing - the best way to better data.
We are passionate about new technologies and we constantly improve our stack. There is always enough room to learn the ropes as we provide internal and external training and education. We are looking for a person who loves high quality of code and who is interested in big sets of data.
90% of the world's data has been produced in just the last two years. Our mission is to help companies with our innovative Data Quality Services. CDQ is the first company in the market to leverage Data Sharing as the best way to better data. Our customers share data quality rules, enrich their data from publicly shared sources, exchange hand-validated data records, and alert each other of data fraud. The result of collaborative master data management: Higher efficiency, shared efforts, better quality, less risks.
With our cloud-based software platform, CDQ can provide Data Quality as a Service – customers master data is monitored and updated continuously, using our Data Quality Tools software or fully integrated with their ERP or CRM systems.
