Developed an NFT marketplace that allows users to mint their own NFTs with custom attributes, categories, and options. The platform utilizes Pinata IPFS for storing JSON metadata and images. Additionally, I implemented an auction feature where users can place their NFTs up for bidding, with auctions automatically closed using a Node.js cron job. Users can also list their NFTs for sale. The marketplace includes advanced filtering options, enabling users to search NFTs based on attributes and categories retrieved from IPFS.
