About Stijn

I help businesses and organizations transform their data into actionable insights.

As a data management professional, I help organizations leverage their data as an asset. I strive for integrated solutions, which touch upon all realms of data management, from data governance to analytics and forecasting.

Additionally, I am capable of working in data analytics projects. I have worked with various languages, including Python, JavaScript and SQL.

I am also a certified SAP S/4HANA Financial Accounting Associate. Within the field of SAP, I have hands-on experience with data migration (Greenfield context) and Financial Accounting.

I am mostly open to ad-hoc requirements and occassionally projects spanning a few months.
