Immigratie- en Naturalisatie Dienst

During 2013 I worked the entire year on the new attempt to build a datawarehouse. My main focus was the design of the data model for the historical storage (Data Vault), and the information analysis to determine what was what, as well as determining how to map the Indigo source system to the historical storage. At the end of the year the solution was up and running. The data marts were very fast and the IND was able to report accurately on historical data, even in the light of continuous change.

Key features: Power Designer, information analysis

Astellas Nederland

In 2012 Astellas, like many pharmaceutical companies, faced the challenge of complying with the EU legislation concerning the evMPD. All information regarding authorized medicines distributed by Astellas was to be sent to the EU before a certain deadline, and all changes to the authorizations had to be provided afterwards within a short timeframe. At first this was designed as a DWH solution, but it ended up as an Oracle Apex solution.

Genexis B.V.

Genexis B.V. is a fast-growing company in The Netherlands that provides a large amount of the FTTH market with smart modulair FTTH-modems. To keep up with the rapid growth they needed to improve the management of their Return Material Authorization process. This also meant managing the masterdata for (potential) customers as well as the delivered products. In order to do this, requirements were analysed, a design was approved and building commenced on a web application that could do this. The system has been fully operational for more than a year without a single incident.
