Challenge: The Carrefour iOS app served over 1M active users across 16 markets, but carried legacy architecture, ballooning app size, and thin test coverage — while the business wanted new capabilities like an AI shopping assistant and unified payments (Carrefour Pay, Tabby/Tamara, Apple Pay).
Approach: Led the migration to a modern Swift/SwiftUI architecture (Repository pattern, structured concurrency, SOLID principles), automated CI/CD with Azure Pipelines and Fastlane, built an AI-driven assistant using ChatGPT for recipe suggestions and smart product search, and introduced a desk-check review process before release.
Result: App size down 28%, test coverage up from 32% to 84%, reported bugs down 58%, and the AI assistant opened a new in-app advertising revenue stream.
