Burger Builder: Custom Burger Ordering App

Challenge

In the competitive food industry, restaurants need innovative ways to engage customers and differentiate themselves from competitors. The client, a progressive restaurant chain, wanted to offer their customers a unique, interactive experience that would allow for complete burger customization while maintaining operational efficiency.

The traditional ordering process was limited to preset menu items, leaving customers unable to truly personalize their meals to match their exact preferences. The client needed a digital solution that would:

Empower customers to build custom burgers from scratch
Provide real-time visual feedback as ingredients are added
Calculate pricing dynamically based on selected ingredients
Ensure a fun, engaging user experience that encourages repeat visits
Seamlessly integrate with existing order management systems

Solution

I developed the Burger Builder App, a dynamic digital platform that transforms burger ordering into an interactive, personalized experience. The application enables customers to craft their perfect burger by selecting from an extensive array of ingredients, with real-time visual updates and instant price calculations.

Bun selection (classic, whole wheat, brioche, lettuce wrap)

Technical Implementation

The application was built using React for the dynamic user interface, providing smooth interactions and instant visual feedback. Redux managed the application state, ensuring consistent ingredient tracking, price calculations, and order data across all components.

Firebase served as the backend, handling user authentication, order storage, and real-time updates. This allowed for quick development and deployment while maintaining scalability for growing user bases.

The payment system integrated Stripe's API, providing secure, PCI-compliant payment processing. This ensured customer payment information remained protected while offering multiple payment method options.

The visual burger builder used CSS3 animations and transforms to create engaging stacking animations, making the ingredient addition process feel tactile and fun. Responsive design principles ensured the app worked flawlessly across desktop, tablet, and mobile devices.
