Lumen

Overview

Lumen came to me with a product people trusted but rarely opened. The goal: make everyday money decisions feel lighter without hiding the numbers that matter.

Challenge

Six years of feature layering had produced 40+ screens, three navigation models and a design debt that slowed every release.

Approach

I mapped every job-to-be-done, cut the IA down to four spaces and built a token-based design system shared by iOS, Android and web. Weekly prototype tests kept the team honest.

Outcome

The redesign shipped in two phases. Weekly active users grew 38%, support tickets about ‘where is…’ dropped by half, and the system now powers two new products.
