Challenge
HighLevel's existing Memberships feature needed modernization to compete with dedicated course platforms (Kajabi, Thinkific). Required mobile-responsive UI, installable PWA, extensive theme customization, rich community features (comments, forums, webinars), and improved accessibility.
Solution
Led comprehensive overhaul: redesigned course player with responsive layouts, introduced Theme Customizer with live preview and multiple skins, built mobile PWA with Capacitor for installable apps, added threaded commenting with rich media, integrated live webinars and group chat, implemented gamification (leaderboards, badges), and ensured WCAG AA accessibility compliance.
Context & Background
Multi-tenant SaaS platform where agencies host courses and communities for their clients. Needed white-label branding, mobile parity, real-time engagement features, and seamless integration with HighLevel's CRM, email automation, and payment systems.
