I approach digital product design from a strategic perspective, balancing user needs, business goals and technical constraints. Early alignment through concepts and prototypes helps teams creating decisions and move forward with confidence across web and mobile products.

kjellwierig-services-accessibility

I design interfaces that work for everyone by considering contrast, keyboard navigation, focus states and scalable typography from the beginning. This result in inclusive products that meet WCAG standards without compromising usability or aesthetics.

kjellwierig-services-designsystem

I see design systems as an infrastructure for product teams. By defining clear foundations, scalable components and shared principles, I help organizations reduce complexity and enable consistent decision-making across teams. The goal is long-term efficiency, quality and sustainable growth.

kjellwierig-services-collaboration

I run an active role in guiding teams through complex product decisions. By aligning product, design and engineering, I help establish clear standards, ownership and shared responsibility for quality. My focus is on creating structures that support good decisions.
