Dual Registration Marketplace App with Chat and Payment Integration

Job ID: 40555033

Budget: ₹2,500 – ₹5,000 INR

I’m looking for an app that supports dual registration (similar to Swiggy/Zomato) integrated into a single app. It will have two roles:
1. Users: Can post their interests or requests.
2. Captains: Available captains can respond to these user interests in real-time.

Features required:
- Dual registration process: Users and Captains (within one app).
- Posting and responding functionality for Users and Captains respectively.
- In-app messaging/chat option for seamless communication.
- Basic payment gateway for transactions.

Looking for modular and clean code with clear documentation, ensuring scalability for adding advanced features later. Pitch me your proposed tech stack, timeline, and deliverables.
