Build a blockchain NFT tracker

We are looking for a blockchain developer to build a Non-Fungible Tokens (ERC-721) tracker, a sort of blockchain explorer. Specifically, we want to track the sales of the NFT called "NBA Top Shot" ([login to view URL]). To do so, you will have to access the Flow Network using their API ([login to view URL]).

We are looking to build something similar to the following sites: [login to view URL] and [login to view URL]

Your first job will be to build backend scraper to retrieve the data in real time from the Flow blockchain and store the transactions in a database. We believe that the scraper should be built in javascript and the data store in SQL but we are open for suggestion.

We will pay by the hour, and we need a blockchain developer that can start right now and work full-time.

When applying, please provide references of previous blockchain projects you've worked on related to blockchain and NFT.
