Financial Services: Dark Mode & Accessibility Overhaul
SecureBank Digital • Financial Services
Complete accessibility overhaul with dark mode that expanded user base by 40% and achieved WCAG AAA compliance.
The Challenge
SecureBank's platform was inaccessible to users with disabilities and lacked dark mode, limiting their potential user base.
Our Solution
We redesigned the entire platform with WCAG AAA compliance, implemented system-aware dark mode, and ensured full keyboard navigation.
