The Challenge
Our enterprise application was built on deprecated AngularJS with a Windows 99-era design system. Users struggled with poor accessibility, inconsistent interactions, and outdated visual patterns that hindered productivity and created frustration. The technical debt was mounting, security vulnerabilities were increasing, and recruiting developers familiar with the legacy stack was becoming increasingly difficult.
