YipYip was contracted by Watertaxi Rotterdam B.V. to revamp their website and incorporate an online reservation system. The goal was to minimize phone reservations and provide users with information in both Dutch and English. The website was designed from scratch, with a few elements from the previous site. An API was developed to interact with the backend. The project team included a project manager, a website designer, a website developer, and a DevOps person when needed.

In another project with Watertaxi Rotterdam B.V., YipYip was hired to develop a custom iOS POS system. The goal was to transition from a manual, hand-written system to a digital solution for managing trips and guided tours. YipYip designed the POS system from scratch, including the IT architecture and graphic design. The team for this project consisted of an iOS developer, a graphic designer, and a project manager.

YipYip was also hired by DoToo, a social app company, for custom backend development and consulting services. The goal was to create a reliable backend solution that could connect to the frontend through a REST API. YipYip developed a custom backend solution responsive to DoToo's specific needs. The team varied from 2-4 people depending on project requirements.
