Eurofiber – 2021

A collection of components designed for the new Eurofiber.

Eurofiber has been a provider of industry-leading digital infrastructure since 2000. Together with the crew at iO, I redesigned their site.

An animation showing the mobile menu opening up to reveal a multitude of links to solution and product pages. At the end of the animation, the menu is closed with a button on the bottom of the phone screen to form a loop.

Eurofiber has many products, which I wanted to present elegantly. No hamburger buttons. Through the new mobile menu, users are able to quickly orient around their many offerings.

An animation showing an overly large cursor moving inside the the frame to click on a card.

I see you looking at that cursor, thinking, "it can't be that big, right?". And you're correct about that. It's fake. But the funnel supporting different sized organisations isn't.

Kapitaal — 2020

They said Helvetica, black and white. We gave them Helvetica, black and white.

Through information architecture, we kept the navigation structure simple as pie. Or hamburger, in this case. Sorry, designer jokes.

Scrolling through pages that contain buttons makes labels act funny. Because, why not be a bit forceful about booking a table?

It is always fun to pretend to work with Ramon & Carlien.

No Seat at the table — 2020

Thumbnail showing a title card explaining No Seat at the Table.

No Seat at the Table is an online platform to exchange stories of gentrification, the housing crisis and the need for spatial justice.

The original bird illustration is created by Rajab Eryigit.

For this site, we created some fancy shmancy intro animations and different ways to discover stories of gentrification.

Do you see that? No hamburger menu! On a mobile screen? No way. Just. Wow!

I like to take the time with clients to nail down certain steps in the design process. Minem and I are going through a review here.

Eneco — 2018

The Eneco app enables consumers to influence their energy bill by offering data on their power usage.

During my time we utilised click data, interviews and surveys to simplify the interface and user flows. We improved the menu through a card sort.

By following the Jobs to be Done model, we focussed most of the redesigned interactions around the goals users have.

We also realised a bigger shake-up of the app through a design sprint.

HR Projectadvies — 2018

As an interim project manager Erik Jan helps large corporates go through organizational changes. The renewed site expresses who he is: an expert with an approach that connects people.

We rewrote and restructured Erik Jan's previous website using a priority guide. We also used the guide to build wireframes. Not that that's related to this guy.

Thumbnail showing 4 combined illustrations.

When in doubt, add more illustrations. In this case, we created some abstract ones related to typical HR practices and skills.

I'm Martijn, a digital designer from Utrecht (NL) with around ⑨ years of professional experience.

While I focus on tinkering with interfaces and designing for curiosity, I appreciate being involved in branding as well. 

I like to think about friction in interaction design. 

Technology is an instrument meant to help us, which means it shouldn’t intrude when we don’t need it. By thoughtfully adding small amounts of friction to well-considered places, I believe that we can strike the right balance between maximising usability and maintaining an appropriate distance.

Another way I’d like to look at design is that it is a way of making the technology we use feel considerate, warm and natural. While this isn’t technology’s default state, I believe that we should use design to give us back some of that warmth. 

This means we should be focused on anticipating and solving a user’s problems before they ever have them. Ideally, a tool should be so intuitive and caring that we forget that it’s technology at all. It should just be there when it’s needed, and absent when it’s not.

Collaboration is essential to create relevant work. In my freelance practice, I experiment with different approaches of collaboration, be it with clients, specialists in related fields and designers new to the game.

I’ve developed a strong interest in socially driven projects by being involved in ones such as restaurant Syr and Parta. It's also why I started lecturing at Communication & Multimedia Design in Utrecht. Are you working on a socially driven project? I’m always open to learn more. ☻
