Vereniging Eigen Huis has more than 700,000 members who ask Vereniging Eigen Huis for help on their houses and to get other benefits, like discounts on insurance.I am working here as a software engineer in one of the many different development teams. With my team we are developing the Insurance propositions, so members can get insurance for their houses, travel and car. Besides the Insurance propositions we are partly responsible for integrating the backend with third party systems and we maintain micro services.We are working with Scrumban with continuous integration (Azure devops and Azure). The development is done with Angular for the frontend and C# for the backend.

I am working as an IT-consultant/software engineer and at this moment I am developing for Vereniging Eigen Huis.

I researched Distributed ledgers for my graduation project. The case that I had to research was a permission system for healthcare. The case was as follows:The patient can give permission to a hospital or doctor (file holder) to show certain data like an x-ray scan to other hospitals or doctors (Consultant).So the Consultant can ask the patient through the Distributed ledger for his permissions. The consultant then gets a list of permissions. With this list of permissions the consultant can ask the file holder for the data he has permission to. The file holder verifies if he really has permission with the patient and then gives the data to the Consultant if the permission is correct.This case has a problem... User data. Because everything you save to the blockchain is kept in the blockchain. this means that everyone in the blockchain can read the information and that is not good for privacy. It is also not possible to encrypt the data and put it in the blockchain, because when the encryption eventually gets broken the data will be open to everyone that has access to the blockchain.I made an architecture with hyperledger fabric, to make the above case possible. To accomplish it I used hashing, asymmetric encryption, and trusted agents with inspiration from Hyperledger Indy.

I mainly worked on DataDossier. A product where people can creature custom questionnaires with a lot of different options. For this project I mostly programmed in C# and AngularJs.

At VPO I did my internship where I programmed a dynamic instruction manual builder with Javascript, C#, Angular, Canvas, Html and Css. With this application you could place images, notes and make multiple layers and pages that could be shown to the user. Sort of a PowerPoint lite and Photoshop lite mix.

For Arbor Media I did a lot of different things but there were two bigger projects.I made a logger for their custom media player implementation. With this logger it was possible to see what people watched and where people would skip or pause the media player. For this data I made a frontend that aggregated the data and made a timeline with all the places where the video's where watched and skipped. I built this logger with C# and ASP.NET MVC for the frontend.The second bigger project was a video exporter in C++. I had to mark the exact points in the video file where the user wanted to cut the video and export it. I made this for a custom video format and with frame loss it was a pretty complex solution.
