Description
Bridging the physical in-store experience with digital browsing for Mexico's leading department store chain.
Context
At the Guadalajara National Swift Community Change Makers Hackathon, we built an app to bridge Liverpool's physical in-store experience with the digital one. The result was a smarter, AI-powered shopping companion that made the store feel more personal.
The Problem
Physical retail has a digital blind spot.
Liverpool is Mexico's largest department store chain, but its in-store experience had no digital layer. Store associates knew nothing about the customer standing in front of them, and customers had no smart way to discover products or get personalized recommendations while browsing the floor.
- Associates had zero visibility into customer preferences or purchase history at the point of interaction
- The existing app was cluttered and difficult to navigate, and discovery felt like a chore
- No bridge existed between the physical loyalty card and any digital intelligence
The Solution
A smarter, AI-powered shopping companion that makes the store feel personal, connecting the customer's digital history to the physical moment of sale through NFC and conversational AI.
Constraints
This was the Guadalajara National Swift Community Change Makers Hackathon, a national-level competition with a strict time limit and a real client brief from Liverpool. The same three-person team, the same all-in approach. Every feature had to run on real hardware, not a simulator.
Key Features
App Redesign
A ground-up rethink of the Liverpool app UI: cleaner navigation, better product discovery, and a layout designed to reduce friction from browse to cart.
Smart Credit Card (NFC)
Store associates can scan a customer's Liverpool Credit Card via NFC to instantly pull their search history and receive AI-generated product upsell recommendations. The physical card becomes a bridge to the customer's entire digital profile.

AI Shopping Assistant
A conversational chatbot lets customers describe what they are looking for in natural language, with no more scrolling through endless categories. The assistant finds it, recommends complements, and adds to cart.

Takeaway & Reflection
Competing at a national hackathon with a real brand brief pushed us to think beyond just building something functional. We had to pitch it as a real product. The NFC integration was the moment that made judges stop and pay attention: it was tangible, immediate, and genuinely useful.
The biggest lesson was how much a clear narrative matters. We had strong features, but the projects that landed best were the ones where the demo told a story. That shaped how I present work ever since.
