For the Moral Markets web portal, which I originally built in 2017 and still manage, I have built a sub-site for a related initiative: the Future Markets Consultation. This sub-site has its own header, footer, menu and color scheme. It thus looks like a separate site, yet content can easily be placed on both this sub-site and the main website.
For the newly established working group on the COVID-19 crisis of the Delft Design for Values (DDfV) Institute I created a sub-site within the existing DDfV site.
The Foundation for Responsible Robotics (FRR) is a non-profit founded by two scholars wishing to create societal impact in their area of expertise. The people involved lacked the time to give the site the update it needed a couple of years after its launch. The improvements that I have made to the site include the header (a banner now immediately informs visitors of their vision) and various newly designed pages on projects done so far (such as the quality mark project and the consultation reports).
I became responsible for the site of the DDfV Institute after it had been designed and built by another agency. I added crucial functionalities (such as an event calendar and filterable member page), re-designed various pages (such as the home page) and developed new content (such as a page introducing design for values). I was responsible for site maintenance and content management for two years, while I also worked as project manager for the institute.
While serving as ad-interim assistant director of the Dutch Research School of Philosophy, I made various smaller and larger improvements to the site, including embedding relevant social media & blog feeds at certain places, adding sharing buttons, a modernization and extension of the home page, and a new menu structure to make room for new content resulting from new initiatives.
