This is some of the work I did at my former employers.
Mijndomein.nl (at Ibuildings.nl)
Furthermore I have worked on carving out parts of their application to micro services and connecting them via HTTP APIs and message queues controlled by a central process manager and setting up a (OAuth 2 based) single sign on solution for authentication between all services and the existing platform applications. I have initiated the use of (Docker) containers which is now broadly adopted for production usage accross the entire platform.
SURFnet.nl (at Ibuildings.nl)
SURFnet provides IT infrastructure and online services to Dutch universities and research institutes. One of the services SURFnet offers is the SAML based OpenConext platform which offers a 'collaborative infrastructure' that allows students, teachers and researchers in the Netherlands to collaborate using online services. As part of the Ibuildings team at SURFnet I did a lot of maintenance and worked on modernizing various components of the platform, improve test and automating deployment and provisioning using Ansible.
Verzekeringssite.nl (now Hoyhoy.nl) (at Ibuildings.nl)
Verzekeringssite.nl offers comparing and taking insurance policies. As part of the team at Verzekeringssite I developed a service that aggregated data retrieved from 3rd party APIs and calculated the most suitable insurance policies based on user input in realtime.
While I mainly focus on backend (web) applications I have done a lot of (campaign) website, CMS and advertisement work for clients like: Vakantieveilingen.nl, FC Utrecht, Fietswereld/Profile, Heineken/Amstel, WebAds and Adrime (now Weborama).
