Enhance Travel Web & iOS App

I’ve built an activity-search and price-comparison web app inside Replit, and the core features are live. Now I need an experienced developer to tighten the codebase and package it for the App Store.

What I need next
• Functionality & performance upgrades – profile the existing code, refactor bottlenecks, add tests, and make the overall experience snappy and reliable.
• Activity-booking API integration – wire in live inventory and pricing from leading activity booking APIs (e.g., Viator, GetYourGuide, Klook or your preferred partner).
• iOS build & deployment – turn the web app into a native-feeling iOS application. Whether you choose React Native, Capacitor, or another modern approach, the end result should be TestFlight-ready with clear release instructions.
• Lightweight backend tweaks – set up any endpoints or caching needed so mobile users get fast responses, even on spotty networks.

Deliverables
1. Updated Replit project with commented, optimised code and a concise README.
2. Fully functional activity-booking API module with environment-based configuration.
3. Signed iOS build plus step-by-step deployment guide.
4. Short hand-off session (video or call) so I can maintain and extend the project confidently.

You’ll fit well if you have proven travel-API experience, modern JavaScript skills, and a track record of shipping iOS apps. Please share any relevant links or screenshots along with a brief outline of the tech stack you’d recommend for the mobile layer.

I’m ready to start as soon as I meet the right person—looking forward to working with you!
