A Web 3.0 developer is a specialist who creates decentralized applications and endorses the theory of change. It is the concept that underlies the concept: the Internet needs to be changed because user data has become a commodity in the hands of giants, there is no information security, and the concept of authorship is blurred. The new Internet is a space where users own their own data and control its use.

What skills do I need to have?

Here are the skills that will be useful for a developer who plans to work within the Web 3.0 concept:

• Strong Web 2.0 skills: JavaScript, HTML, CSS, design, understanding of data analytics;
• understanding of smart contracts, blockchain, and cryptocurrencies;
• Solidity and Rust skills;
• experience in developing dApps on the Ethereum network;
• understanding of blockchain architecture of protocols and networks: TCP/IP, HTTP/HTTPS, JSON RPC API;
• knowledge of Machine Learning.

Responsibilities and roles

• A front-end developer in Web 3.0 will create user interfaces for decentralized applications. Starting skills are HTML, CSS, and JavaScript.
• Back-end developers will create blockchain servers that host application user interfaces. Starting skills are NodeJS or other server languages (Python, Ruby).
• A Full Stack developer is a universal specialist who will create a concept and fully implement it.
• A mobile app developer will create products that allow users to interact and manage data on the blockchain. His or her responsibility is to ensure the stability of applications on iOS and Android platforms.
• The data scientist will analyze large amounts of information to study trends in user behavior. In addition, they will analyze the impact of these trends.
• A Machine Learning Engineer will develop algorithms to create predictions based on data. This is necessary to improve productivity and user experience.
• A DevOps engineer will maintain the system infrastructure and ensure the reliable operation of all components.

What tasks does an IT developer solve in Web 3.0?

The IT engineer of the Internet of the future is primarily a specialist in creating metaverse and separate three-dimensional worlds within them. He is also responsible for prototyping and developing programs, applications, and games on the blockchain.

A Web 3.0 developer creates worlds and develops the mechanics of user interaction with cyberspace. That is, they develop user space and customize opportunities for communication, leisure, business, and work.

A development engineer also creates consensus protocols. This means a set of rules for all blockchain participants. With the help of these protocols, transparency of actions can be guaranteed.

In the process, the ecommerce niche needs to be adapted to Web 3.0. This is already happening: brands are presenting three-dimensional electronic collections, and artists and buyers are actively cooperating on NFT platforms. The next step is to work on processes that will help monetize products.

An additional responsibility of the developers of the new Internet is to monitor retention: the rate of user retention. To do this, it is necessary to identify patterns, processes, and phenomena that affect the amount of time users spend in the meta-universe.
