Throughout my life I've been looking for opportunities to work with, and as, a team of talented, motivated people on a joint goal. From building product team(s) at Mimi, creating a company (Atium) that builds human connections in remote teams, to now enabling teams as a product design and management consultant.

Early in my career I realized: It's all about people. Although I'm a bit of an introvert, I strive to create the magic that is realized when you work together with other talented human beings on something with purpose. Sharing ambitions, but also challenges and being present as full humans.

Created a portfolio
Designed a portfolio
Developed my portfolio. Although not yet entirely finished it’s ready for the world!

During the design of the portfolio I tried to really think about ‘what would a hiring manager like to see?’ and at the same time ‘what do I want to bring across?’. Because in the end although the hiring manager might want to see stellar visual design, underlying that want is the need to get a good grasp of my skills. If I don’t excel in visual design then I should also not want to highlight that aspect of my work. 

Anyway, that led me to focus on case studies rather than just dumping screenshots of my work. The positive side is that I can really better explain how I think and work. The negative side is that they take a lot longer and thus I only have 1 completely finished on there for now. 

Because of the same reason I also built this initial dialog that asks people what they’re interested in so that I can highlight those aspects within the portfolio. Unfortunately I haven’t actually gotten around to highlighting anything. But the hiring manager will have to answer the questions.

Designed a feature
Prototyped an App
Designed (and created front-end prototype) of a proposed new profile page for Atium.

Main goals:
* Show a history of activities, to improve the value of the answers that people give.
* Give some high-level insights of how connected someone is to their team.
* Provide a place where people's profile lives.


Note: The profile images are randomly generated, so sometimes a little weird.

Started a new UX project
Started working on a project for Koos Service Design in which we'll develop innovative UX concepts for 5 different (parts of) products that help schools choose their learning methods and order the books for their students. As well as products for students to manage that process, including handing in the books again at the end of the school year.

Launched a game
After sweating a few of the details for a little too long, like adding the splash animation, but also counting the amount of votes correctly, we finally launched Two Truths, One Lie. Although not yet finished, it's our best executed game till now (imho).

Created a product prototype
Built UI components
What: Created prototype for our ice-breaker game Two Truths, One Lie.
The problem: When people are 'put on the spot' it can be hard to come up with good statements.
The solution: Providing a bit of inspiration can go a long way!
Tools/tech: This is a css/tailwind front-end implementation. For the actual product I'll convert this to be used in our VueJS app.
