Nqueries

A social platform dedicated to people that use media content (video, audio, text, images) on a daily basis. This tool allows users to create several types of polls to gather responses from anybody using the platform. I led the back-end development of the app and oversaw the infrastructure. The app is still under development.

Grouptickets

I developed a web application that served as an alternative to Facebook groups for people who wanted to get a group discount while traveling by train in the Netherlands. The national train company had a group discount for people traveling to the same destination from different parts of the country. They were using Facebook groups with ~10,000 users each for coordinating travel on specific days to benefit from the discount. The app made it way easier to group up with other people. You could search for groups for a specific day, create a new group, and communicate using the comments section from each of the groups. The web application grew quickly and reached 70,000 registered users in four months. It showcased in the news in the Netherlands.

CrossNG

This is the sales platform of Porsche and Volkswagen. I collaborated with the team working on the platform. My main role was the management of sales documents and the integration with 3rd-party software, which could handle the same type of documents.
