Solidity Developer for NFT Web3 Marketplace

As an outlet for crypto enthusiasts, art collectors, and sport fans, we're eager to develop a Web3 marketplace. This platform must be efficiently built with:

- User authentication, ensuring only registered users can partake in marketplace activities.
- Smart contract integration, guaranteeing secure transactions.
- Smart contract creation
- Decentralized storage, endorsing data ownership and privacy.
- NFT creation & minting, allowing us to create unique assets to be added to the marketplace.
- Credit card payment feature, facilitating easy purchases (Mercado Libre integration for latam is a plus).
- Custody of NFT to stay within user accounts till transferred to personal wallets.

We aspire towards a minimalistic and clean user interface to cater to ease of navigation (We have some designs allredy made) and clarity. If you're a solidity developer familiar with these features and have a knack for creating user-friendly platforms, we want to hear from you! Prior work with NFTs and blockchain technology will be advantageous.

We require the flexibility for multi-client usage, necessitating the incorporation of a customizable backoffice. This backoffice should empower administrators to configure images, colors, and available smart contracts within the marketplace to cater to the unique branding and requirements of different clients.
