Hi, I’m Daniel. A Lead Product designer passionate about shipping high converting products at scale, and leading designers to become builders.
I focus on building high-converting digital products by turning complex requirements into clear, scalable designs and systems.
Currently leading the design team at Yellow Card, where we build the product businesses across Africa use to move money across borders and between currencies.
My day to day involves working closely with product and engineering stakeholders to simplify complex workflows, reduce delivery friction, and build solutions that perform reliably at scale.
I believe my job doesn't end as a designer until the product is live, well performing and hitting set goals and business metrics
