How do I make a NFT platform like OpenSea?

First, you can choose a blockchain that supports NFT minting and trading, then create a set of smart contracts from the ground up to enable NFT exchange and unique ownership recording, and then create all the back-end features for the crypto marketplace. If you thought this process would take more time and money, you would move on to the white-label solution providers who will build your marketplace with the help of a customizable OpenSea clone script at a lower cost than making it from scratch.
