Finish SparkLink Mobile App

I already have a clickable prototype of SparkLink with every screen, flow, and logic laid out in Base44; now I need that design translated into a production-ready mobile app for both iOS and Android. All visuals, user journeys, and matching formulas are prepared—I simply need clean, maintainable code that mirrors the prototype pixel-for-pixel and function-for-function.

Core scope
• Integrate Email, Google, and Apple authentication.
• Build a lightweight backend that stores both questionnaire responses and user profile data.
• Implement the straightforward matching algorithm exactly as documented.
• Add a basic chat / connection module so matched users can talk.
• (Optional) Handle submission and compliance for Google Play and the App Store.

I can send you access to Base44 - I want to use the majority of the code and package it as an app (web app) for the App Stores (iOS + Android).
Send a brief outline of your proposed tech stack, estimated timeline, and fixed price. If everything aligns, we can get started immediately. Looking forward to seeing SparkLink come to life together!
