Hi, I am David.


Empowering Small Merchants

At SumUp — a FinTech with 3,200+ employees and a presence in 34 markets — I am a Lead Product Designer who improves the way merchants send invoices and get their accounting done easily. I achieve this by having a two-folded role as Design Manager and Individual Contributor.


Data-Driven & User-Centered

Without data, I'd be just another person with an opinion. I like to have a continuous conversion with users and run one or two research studies per quarter. In addition, I am obsessed with data to understand actual user behavior and the impact we had as team. Tableau, Google Analytics, Google Sheets, those are my tools on a weekly base.


Product Strategy & Roadmaps

I look at the end-to-end journey, identify opportunities, and collaborate across tribes to improve products & services. Within my product domain, I contribute to the overall roadmap and product vision. Within the team I work closest with, I help prioritize and set requirements, as well as keep an eye on how our product differentiates itself from the competition.



I believe that user-centered design and cross-functional collaboration transforms digital products and services. I challenge the status quo, drive reinvention, and focus on outcomes, not output.
