Problem

The biggest challenge was that the product was nearly 10 years old and had accumulated significant UX debt. The development team had limited experience working with dedicated product designers, resulting in inconsistent interfaces, weak user flows, and an outdated information architecture. Since the application relied on a tightly coupled legacy architecture, fundamental structural changes were technically impractical, requiring every design decision to work within existing constraints.
