Web3.js is an open source software library that helps integrate with decentralized applications built on Ethereum blockchain technologies. As Ethereum is built on blockchain, Web3.js works as a bridge between the Ethereum blockchain and its users without transcending any rules or data from the blockchain network.
A Web3.Js Developer is an experienced programmer for building decentralized applications using Ethereum development framework and the Javascript library, Web3. When developers use Web3.js, they can craft secure and reliable applications upon a wide-scale peer-to-peer blockchain network with the help of a trustless system of data storage and transfer.

- Creating user authentication features on existing web apps
- Setting up marketplaces for NFTs
- Integrating ETH payment systems with React dApps
- Connecting web sites to TikTok pages
- Crafting smart contracts on Ethereum technology
