About the Project

We're building a cutting-edge vacation rental search and booking platform specifically designed for winter sports enthusiasts. This platform will aggregate accommodations from multiple providers (Interhome, Villa4You, Summit Travel) into a unified, fast, and user-friendly experience.

The Challenge

You'll architect and build a platform that handles complex multi-provider data integration while delivering exceptional search performance and user experience. This isn't just another booking site—we're creating a sophisticated system that normalizes data from REST APIs, JSON-RPC, and XML feeds into a seamless search experience.

What You'll BuildCore Features

  • Intelligent Search System
    : Flexible date search (no-date search, period ranges, pre-filled defaults) with advanced filtering capabilities
  • Multi-Provider Integration
    : Unified data layer connecting REST APIs, JSON-RPC, and XML feeds from multiple accommodation providers
  • High-Performance Architecture
    : Sub-2-second search results with smart caching strategies and optimized data queries
  • State Persistence
    : Seamless navigation that maintains search context, filters, and scroll position
  • Advanced Filtering
    : Real-time filtering by amenities, distance to slopes, capacity, pet-friendly status, and more

Technical Architecture

  • Frontend
    : Webflow + Wized for dynamic interactions, vanilla JavaScript for state management
  • Backend
    : Supabase Edge Functions, normalized database schema
  • Data Pipeline
    : Robust ETL system with retry logic, logging, and error handling for provider integrations
  • Performance
    : CDN-optimized images, intelligent caching (edge/KV), lazy loading, sub-200ms interaction times

Required SkillsMust Have

  • 2+ years
    of full-stack development experience
  • Strong proficiency in
    JavaScript/TypeScript
  • Experience with REST APIs, JSON-RPC, and XML parsing
  • Database design and optimization (SQL, indexing strategies)
  • Supabase
    or similar backend-as-a-service platforms
  • Performance optimization and caching strategies
  • Responsive design and cross-browser compatibility

Highly Valued

  • Multi-provider integration experience
  • ETL pipeline development
  • Edge computing and serverless architectures
  • SEO technical implementation (structured data, sitemaps)
  • Experience with booking/rental platforms
  • Understanding of Core Web Vitals optimization

Technical Challenges You'll Solve

  1. Data Normalization
    : Create a flexible schema that maps diverse provider formats into a unified structure
  2. Search Performance
    : Build sub-2-second search with complex filtering across thousands of properties
  3. Provider Resilience
    : Implement graceful degradation when providers fail
  4. State Management
    : Maintain search context across navigation without framework dependencies
  5. Real-time Filtering
    : Debounced, instant filter updates with
