Work
10+ years experience in fintech, developer tooling and marketplaces.

Approach
When the problem is messy, ambiguous, and business-critical, I step in as a hands-on designer to cut through complexity and get things moving. I align teams, surface what really matters to users, and use prototypes to create momentum and push toward agreed business outcomes.
Co-creation
I bring stakeholders in early so we move forward and learn together.
Prototyping
I combine research and data to turn uncertainty into a clear path forward.
Craft
I design products that feel intuitive because they map to the way people think.
Collaboration
Partnership and guidance, in their words.
Marc was one of the best hiring decisions I've made. I loved working with him, especially when pair designing. His thoughtfulness and willingness to explore ideas and really figure out what would work for users in a complex space made ever conversation fun and end up in a much better place.

About
I didn’t start out as a designer. My career began in investment banking after earning degrees in mathematics and business. While numbers made sense, I craved more creativity and impact. A shift to tech as a Product Manager introduced me to design. Creating wireframes in Balsamiq and reading The Design of Everyday Things showed me that design is about solving real problems, not just aesthetics. I was hooked on UX and haven’t looked back since.
I’m a father of two boys, an enthusiast for photography, natural wines, hiking and an avid runner. When I’m not designing, I'm probably building LEGO with my sons, cooking, or watching a sci-fi show. I’ve been a Londoner since 2009 but whenever we can, my partner and I are traveling to discover new culinary experience or immerse ourselves in nature.
