Robert has developed a lot of bespoke applications for customers in and outside the Netherlands. Examples of these systems are:

• CRM systems
• HRM systems
• Time tracking
• Project management
• Order management and Invoicing
• Document processing
• Registration and prescription system for optics stores
• Student administration
• Course administration
• Office add-ins for accessing data in accounting systems
• Transport Company administration
• Competency Management
• Front end for Stable Automation system
• Hotel Reservation system
• Member administration speech therapist union

Most if these systems work together with other systems such as accounting systems. Robert has a great deal of expertise in importing from, exporting to or reading information from these systems. If there is a published API that Robert will use that. Otherwise he will develop his own API to read/write to these systems. Examples of the accounting systems he has worked with are Exact (DOS, Windows, Globe), Grote Beer, Unit 4, Multivers and Accountview.

During the development of the above systems Robert has created a couple of data access components. When he showed these to other developers he was asked to start selling these as products. This is how he started selling his products Vo2Jet, Vo2Btrieve and Vo2Ado.
