Joan Martí Diez

With 16+ years designing complex digital products across fintech, automotive, B2B platforms and marketplaces, I bridge design strategy and engineering to build experiences that are both usable and scalable. I specialise in design systems and product design for financial and trading platforms — environments where precision, consistency and performance directly impact business outcomes. I've helped organisations reduce design debt, accelerate product delivery and align distributed teams around shared design language. My background spans multiple European markets, which means I bring a cross-cultural perspective and the ability to adapt quickly to new domains, teams and constraints. What I bring beyond craft: I mentor designers, define design principles, and act as the connective tissue between product, engineering and business — turning ambiguity into structured, deliverable solutions. Currently open to two types of opportunities: a Senior or Lead Product Designer / Design Systems Lead role within a product organisation, or freelance/consulting engagements where I can support teams on design systems strategy, UX audits, or scaling design practices — typically project-based or part-time.
