Key Features

  • Crowdsourced Rent Data

    Designed a user interface for users to contribute and access real rent prices, hidden fees, and negotiation options.

  • Location-Aware Interface

    Designed a user-friendly, location-aware interface using SwiftUI and MapKit, allowing renters to easily find and compare listings in their specific area with custom map annotations and interactive selections.

  • Interactive Location Services

    Integrated CLGeocoder for real-time address-to-coordinate conversion with interactive map previews. Users can search for addresses and instantly see location pins update on the map, making it easy to verify and submit accurate rental data.

  • Backend Architecture Design

    Designed comprehensive backend architecture with Supabase client integration, REST API endpoint specifications, and PostgreSQL database schema. The planned architecture ensures scalability and data consistency for future production deployment.

Technical Implementation
