At your home or office

Even though most issues can be resolved remotely, some require our physical presence at your home or office to get them resolved. If necessary, also outside office hours or during the weekend.

About Kalf ICT Services

My name is Vincent Kalf and I am the founder of Kalf ICT Services B.V. I live in Amsterdam. Computers have always had my interest. From a young age, next to school and practicing kayaking, I was engaged in repairing computers, creating websites, setting up networks, automated back-up solutions and so on.

Since 2007, I have used my knowledge to support private clients and companies in solving their IT-issues. In the years that have followed, the need for my services - also in size and complexity - has only grown. The demand has also shifted more and more from private clients to companies. However, private clients still make up a significant part of my clientele.

Because of this, I decided to continue with Kalf ICT Services full-time after ending my professional kayaking career and graduating with a Masters in Accounting and Control from the Vrije Universiteit in Amsterdam. I also discovered the demand for knowledge on the cutting edge of IT, financial processes and cybersecurity, something I have been able to support many companies with already. Solving continuously different IT-issues and having satisfied clients continues to give me much satisfaction.

Feel free to get in touch to discuss your question or issue, also outside office hours.
