Back end developers deal with working with the server side of web applications. They are responsible for data processing and storage, database management, and system security and scalability. Back end developers often use programming languages such as Python, Java, Ruby or PHP, as well as various frameworks and technologies such as Node.js or Django.

Full stack developers are developers who have experience and expertise in both front end and back end development. They can work on both the client and server side of web applications. Full stack developers are able to create fully functional web applications from start to finish, and have more flexibility and the ability to work on different aspects of the project.

As a result, each of these areas of development has its own characteristics and requires specific skills and knowledge. The choice between front end, back end and full stack development depends on your interests, preferences and desired career prospects.

What is the difference between front end, back end and full stack developers?

Front End developer is responsible for creating the user interface of an application on the web. His job is to create a beautiful and functional look and feel that the user will interact with. At the same time, it should be taken into account that the site should be adaptive and adjust to different types of devices and screens.

Back End developer deals with the development of the server side of the application. He is responsible for data processing and storage, as well as for the business logic of the application. Back End developer uses specialized programming languages and databases to create functionality that the user does not see but interacts with, such as registration, authorization, sending and receiving data.

Full Stack developer has knowledge and experience in both Front End and Back End development. He or she can work on both the client and server side of the application. Full Stack developer can create a complete application from start to finish as well as make changes to existing projects. Being proficient in different technologies and programming languages allows a Full Stack developer to be more flexible and efficient.

Thus, the difference between Front End, Back End and Full Stack developers lies in what competencies they have and what part of the development process they perform - work with the client side, server side or in other words, the entire application development cycle.

Responsibilities of a front end developer

Front end developer is responsible for creating and maintaining the client side of a web application. He deals with the development of the interface that interacts with the user.

Design: Front end developer creates the structure and appearance of the web page using HTML and CSS. He is responsible for the proper display of elements on different devices and browsers and creates a responsive design.
Interactivity: Front end developer uses JavaScript to create interactive elements on a web page. He can develop autocomplete functions, form validation, animations, sliders, and other user interaction elements.
Optimization: Front end developer optimizes web pages to improve their performance and loading speed. He minimizes file sizes, optimizes images, uses caching and other techniques in order to improve the user experience.
Testing: Front end developer is responsible for testing the created interface on different devices and browsers. He checks that all elements work and display correctly on different platforms.
Collaboration: Front end developer works closely with designers, back end developers and other team members to create and maintain the web application.

The Front end developer should be proficient in HTML, CSS and JavaScript and have a good understanding of user interface and user experience. Knowledge of modern web application development frameworks and tools is also essential.

Back end developer role

A back end developer is a specialist who handles the creation and maintenance of the server side of a web application. He is responsible for working with databases, handling requests from users, and all the logic of the application on the server side.

The tasks of a back end developer include:

Designing and creating databases and optimizing them.
Creation of API (Application Programming Interface) for interaction of the application frontend with the server.
Developing algorithms for query processing and application logic.
Ensuring data security, including protection against SQL injection and other attacks.
Optimization of performance and scalability of the server part of the application.
Testing and debugging of the application on the server.

Back end developer has to use various programming languages such as Java, Python, Ruby, PHP and others, as well as frameworks and development tools.

Front end development is responsible for creating the interface of the user part (web page or web application) that the user sees and interacts with. Full stack developer is proficient in programming languages such as HTML, CSS and JavaScript and is able to create a beautiful and user-friendly user interface.

Back end development, on the other hand, is responsible for creating and handling the server side of a web application that processes queries, interacts with databases, and executes business logic. A full stack developer understands server-side principles and has experience using programming languages such as Python, Ruby, Java or PHP to develop server-side code.

A full stack developer is able to work with both front end and back end developers, allowing them to provide deeper integration and consistency between the client and server side of the application. Having experience in both areas of development allows a full stack developer to better understand the project as a whole and make more informed decisions.

Full stack developers have a wide range of skills, which makes them valuable members of the development team. They can be involved in all stages of development - from interface design and look and feel to server tuning and performance optimization. Thanks to their versatility and ability to combine different technologies, full stack developers can create complete web applications on their own or in collaboration with other specialists.

How to choose the best option?

Choosing the best option between front-end, back-end and full-stack developers depends on your goals, skills and preferences. Here are a few factors that can help you decide:

Your interests and skills: If you prefer working with user interface and design, then front-end development may be a better choice for you.
