I started Gebakplaats in 2019 as a non-commercial hobby baking platform where hobby bakers could offer their baked goods for sale to people in their neighbourhood who were looking for pastries. In 2020, the idea emerged to link a charitable cause to the baking activities in addition to the sales component. In collaboration with the Food Bank in De Bilt, they began baking cakes for children’s birthdays in families that cannot afford to buy a festive cake. This wonderful project quickly received a lot of positive attention on social media, and within a few months, with the help of several enthusiastic coordinators and many fellow hobby bakers, the initiative expanded to multiple locations in the Netherlands. At present, cakes are being baked in many cities for children from low-income families. The number of hobby bakers signing up to bake for this good cause grows daily. The “baking for sale” component was discontinued in 2025 to fully focus on the baking-for-low-income-families initiative.
Since my mother is now the chair of the foundation, I was no longer allowed (for legal reasons) to be part of the board. Therefore, I am now only responsible for this website.
The Calendar Clock is a clock with a messaging functionality that supports those with reduced awareness of time and/or memory problems. It shows the part of the day and time (analogue or digital) and shows important agenda items, reminders and/or personal messages. These messages can be created/edited/deleted on the user's device.

Reduced clothing returns, increased conversion and lower CO2 emissions. That is what we strive to accomplish at SizeBuddy.
SizeBuddy is your personal tailor that knows exactly which size you should order.
Together with Maurits Graaf and Diederik van Zantwijk, I have created SizeBuddy as a tool to help both clients and retailers. Using Artificial Intelligence we predict the clothes that fit you best, simply based on what you are already wearing.
Palbum offers a fresh new way to share adventures with groups of friends. People can customise their own profile, make a group profile with friends and upload albums and photos. With two fellow students I further developed Palbum and we ended up reaching the finals of the TU/e contest together!
I am a data engineer / software engineer who is passionate about entrepreneurship and driven to acquire new skills through product development. I find immense satisfaction in contributing to projects that hold societal value. Witnessing enthusiastic users actively engage in co-creating my products is a source of inspiration for me. I like that the diverse range of products broadens my skill set in non-computer related areas.
I'm especially interested in the data-intensive systems domain, which I am currently writing my thesis in. I am happy that I am able to combine my wide knowledge in different computer science domains and I am thrilled by the prospect of contributing meaningfully to this dynamic field.
