I worked as a Data Scientist in the Big Data department and I worked as a software engineer for the data gathering department of the CBS in Heerlen. Whilst working here, I created many valuable insights out of large chunks of structured and unstructured data. I implemented multiple machine learning algorithms to gather information from various (big) data sources. For example using specific big data sources within the CBS, we trained a random forest machine learning algorithm, so that it could predict a certain statistic within half a percent of the actual value. This was close enough so that a complete survey, which was very expensive and time consuming, could be cancelled. Furthermore I created many dashboards to keep track of survey responses for both companies and individuals, to make sure important key performance indicators were achieved during ongoing surveys. These dashboards helped to keep track of response targets. If these targets were not achieved, incentives could be used to still meet the objectives. I was also part of a team that completely updated the whole infrastructure and software landscape for the data gathering department. I created and coupled many databases, both in SQL Server and Access. I helped to implement a new enterprise workload automation system within our department (400+ people).
