India-centric Ecommerce Marketplace Development

I'm looking to create a unique ecommerce marketplace tailored for India. Most of the codebase exists with node as backend with microservices, react/flutter on front end. I need a Full Stack Developer to take ownership and take the work forward.

Key Features of the Marketplace:
- Dual Seller Platform: The marketplace will accommodate both professional retailers and individual hobbyists, fostering a diverse range of products and price points.
- Multi-faceted Payment Options: The platform will support various payment methods including Credit/Debit Cards, UPI/Net Banking, and Cash on Delivery. Experience with integrating these payment systems in an ecommerce platform is crucial.
- Robust User Authentication: A secure and seamless user authentication system is key. The platform will require Email and Password, Social Media Login, and Mobile Number OTP verification. Experience with implementing such authentication measures is highly desirable.

Ideal Skills:
- Ecommerce Development
- Payment Gateway Integration
- User Authentication System Implementation
- Marketplace Development
- Understanding of Indian Ecommerce Landscape

Experience with creating a platform similar to Amazon.com for retailers would be highly beneficial. Please provide examples of relevant past projects in your proposal. Utilize AI to modernize for additional features.
