Dolphia Nandi Arnstein

Design Leader

For the past 8+ years, I've built digital experiences from the ground up - starting as sole designer for an entire city government and growing that into a full design practice serving 110K+ users across 46 departments. I've designed everything from snow centers to HR platforms, established design systems where none existed, and made accessibility standard practice.

I thrive on solving complex problems, partnering with product and engineering teams, and turning research insights into measurable business impact.

I work fast, strategically, and make design a driver of business outcomes - not just pretty pixels.
