Hi! I’m Thomas, a UX designer with a passion for User Research.
I transform hunches to actionable insights. With over 100+ user interviews conducted I love testing risky assumptions, or better said, I love hanging out with unpredictable, irrational, complicated humans that are gaining value from the products and services that I design.
Throughout my career I’ve collaborated with a diverse set of brands, including Philips, Signify, CM.com, and Sendcloud. With a Master of Science in Industrial Design, and a PhD in Interaction Design, my projects always have a strong focus on a deep understanding of the people using a product and creating frictionless experiences that are pleasant and memorable.
Occasionally I code and create websites, logos, and visual identities. I have been creating designs professionally since 2012, starting as a freelance graphic designer, I’m currently working as Senior User Researcher at Sendcloud, collaborating with 5 feature teams focusing on automating the shipping process for e-commerce retailers.
UX designer
I design with empathy and enthusiasm. I thrive in complex design challenges with multiple stakeholders, and I never shy away from a new challenge. I build relationships with designers and stakeholders to establish design practices that people want to work with and be a part of.
Assumption validator
I continuously track user needs to quickly identify and validate opportunities, helping us stay lean and competitive. I prioritise testing the riskiest assumptions first with creative experiments. Moving from hunches to confident, user-informed, and actionable insights.
User researcher
Humans are the best. I love hanging out with unpredictable, irrational, complicated humans that are gaining value from the products and services that I design. With a PhD in interaction design, I have deep knowledge of mixed method research methods. GOOB is my jam: I only start designing after hanging out with the people that will use my designs.
Design thinker
Uncovering big ideas gets me super excited. I love bringing cross-disciplinary teams together to collaboratively explore solutions and solve problems. I have extensive experience planning and facilitating workshops.

I am a design researcher with particular interest in how people experience interactive IoT systems in their future everyday. With these complex systems, design becomes part of a stakeholder network that jointly creating value for people. I regard people as humans (not users) and considering their aspirations, believes, and experiences. By exploring the context in which these people behave through observations and actively involving people in research, I aim to design technology that fits people’s routines and practices.
I am a creative thinker and a team player specialising in human-centered, qualitative, and in-situ research, with a particular interest in understanding the role of technology in everyday life. I approach research hands-on by realizing high-end prototypes and evaluating them with people in their everyday life.
