I’m building a travel-style companion that asks a traveller for their destination, region, and trip type—beach, mountains, city, wedding, trek. On the spot it analyses real-time weather, local culture, the occasion, plus the user’s declared style preference (we begin with Casual) to serve a complete head-to-toe look: clothing, shoes, accessories, make-up, even the right SPF. Every recommendation is product-specific so a single tap can drop the item into a cart inside the app. The core of the project is a personalised outfit recommendation engine. I need you to design and implement the full stack: • Front-end (iOS / Android or cross-platform) that captures the user inputs and displays rich outfit boards. • Back-end services that pull weather data, store cultural style rules, and run the recommendation logic. • A lightweight in-app marketplace driven by affiliate feeds and direct brand catalogues, so users can purchase what they see without leaving the app. • A brand onboarding portal that lets fashion labels upload inventory, manage stock, and connect their payment / fulfilment accounts. Success for me means: a smooth onboarding flow, accurate casual-style recommendations that feel tailored to location and climate, and a checkout that completes without leaving the app. If you have prior experience with fashion e-commerce APIs, recommendation engines, or payment integrations, that will help us move fast.
