The technical execution focused on three core pillars: reliability, accessibility, and polish. I addressed critical user flow blockers that prevented progression through the AR experience, such as non-functional retry buttons, overlapping UI elements on Android, and navigation dead-ends when camera permissions were denied. The product scanning system was refined to reduce false-positive "Turbulence Detected" errors that frustrated users trying to unlock characters. Device and browser compatibility checks were implemented to gracefully handle unsupported configurations, while orientation restrictions guided users toward optimal scanning conditions. Every interaction was scrutinized to ensure pixel-perfect alignment with design specifications, creating a premium AR experience that felt as polished as the Marvel brand itself. The result was a robust web AR application that scaled to millions of users while maintaining the magic of bringing superheroes to life through everyday Coca-Cola products.
