What does a back-end developer in Web3 do?
A back-end developer in web3 typically works on the server-side of a web application, using technologies that are specific to the decentralized web (also known as Web3-related)
This might involve building and maintaining the infrastructure that supports decentralized applications (dApps), or developing the underlying smart contracts and blockchain-based systems that power those dApps
In general, the goal of a back-end developer in web3 is to create the technologies and tools that enable users to interact with the decentralized web in a secure and seamless way.
