About
Experience strategy for products people can trust
I’m Daniel César Vieira, a senior customer experience and product design consultant. I help teams turn complex products and emerging technologies into clear, useful experiences — with design connected to product outcomes.
My work combines customer experience strategy, product thinking, research and interaction design. I bring structure to complex problems and help teams move from insight to decisions, prototypes and delivery.
20+ years across digital products and services
For more than 20 years, I’ve worked across customer experience, product strategy, research and digital design. My experience spans healthcare, financial services, mobility, media and technology, with teams and organisations including Sony, Younited, Leetchi, Honda Research Institute Europe and CNRS.
I’m comfortable working across disciplines and connecting user needs, business priorities and technical constraints. The goal is not design for its own sake: it is a product experience that solves a real problem and creates value.
Current focus: AI, healthcare and financial services
Today, I focus on AI-enabled products, especially in healthcare and financial services. I help teams identify valuable use cases, shape end-to-end journeys, make complex capabilities understandable and build the conditions for adoption and trust.
Useful AI depends on more than model capability. It needs relevant context, clear interaction, reliable evidence and appropriate human oversight. These principles guide the way I approach AI product experiences.
How I work
I combine strategic thinking with hands-on design. I work with product, business, research and engineering teams — from early framing and discovery through journey design, prototyping, validation and delivery.
My approach is collaborative, evidence-led and focused on clear priorities. I help teams make better decisions, reduce complexity and connect experience quality to product outcomes.
