React Native CLI Developer for Marketplace App

About the Current App:

Marketplace app currently running on iOS and Android with Firebase/Firestore backend infrastructure.

Goal:

We are rebuilding the mobile app using React Native with a strong focus on:

• clean architecture
• vendor independence
• scalable marketplace systems
• future backend portability
• multi-surface platform evolution

This is not just a UI rewrite. The goal is to build a long-term platform foundation for mobile, web, and future expansion into multiple categories and regions.

Role

We are looking for a senior React Native developer experienced in:

• React Native CLI
• clean/layered architecture
• scalable mobile applications
• backend/API integrations
• marketplace-style applications
• long-term maintainable systems

This role involves rebuilding the current app architecture while preserving feature parity and preparing the platform for future migration from Firebase/Firestore to PostgreSQL-based infrastructure.

Technical Direction

We strongly prefer:

• React Native CLI
• vendor-independent architecture
• clean abstraction layers
• portable infrastructure
• self-hostable or replaceable systems

We want to avoid:

• hidden vendor lock-in
• Expo-managed infrastructure dependency
• tightly coupled Firebase architecture
• business logic spread across UI/screens

Initial Scope

Milestone 1

Build React Native mobile foundation for iOS + Android, introduce domain entities + repository interfaces, and remove direct Firebase access from screens/components.

Milestone 2

Rebuild core marketplace flows in React Native using UseCases, repositories and canonical Posting domain model. Standardize state management, navigation and data flow architecture.

Milestone 3

Connect React Native to backend contracts and introduce Firestore compatibility/mapping layer from current structure to canonical domain models.
