What I'll bring to the table

Research & Validate

Arguably the most important part of being a UX designer. If you don’t understand the problem, you can’t build a solution. I’ve interviewed, read countless studies and analysed data to build something that makes sense for a user and the business.

Design & Build

With a good understanding of the problem, I design digital products that adhere to brand guidelines and help the user get what they need from start to finish, making sure to test and validate through research. With a passion for branding and graphic design, I push pixels using modern tools like Figma, Sketch, and build them using HTML, CSS and various JS frameworks.

Team Player & Leadership

I've organised design sprints, mentored designers, presented to stakeholders while remaining open to feedback and improvement.


Work experience

Booking.com

Role: UX Designer | Aug 2016 - Oct 2020

As a UX Designer for Booking, I worked with different Agile teams in on both guest and partner facing products. During this time I gained a lot of experience in UX research and validation, mostly through A/B testing, gaining a deep understanding on which UX solutions work best.

Responsibilities within teams varied, from research to designing and coding/building digital products. Created user flows, low- and high fidelity designs, validated prototypes and mock-ups through usertesting and interviewing users, as well as communicating/presenting with stakeholders and team members.

Genkgo

Role: All-round Designer | May 2012 - Jul 2016

As a designer for Genkgo, I was responsible for designing and coding websites for clients, as well as UI/UX design for Genkgo software. I managed projects, sat down with clients and was often the first to pick up the phone. I was closely involved with the founders of the company, helping them define their product under the name of Verenigingenweb.
