What Does a Backend Developer Do?

  • Who is Backend Developer, What Does He Do?

    Backend developers are software developers who plan and code the systems running in the background in software projects and ensure that the system works properly.

    This profession is becoming more and more common and is of interest to many young people. Playing both a technical and an important role, backend developers are closely related to the software field and manage important components in the background of a website.

    Backend developers create and realise the servers, applications, databases and communication tools that must be present on websites. These people are usually individuals with software training and technical skills. They establish connections between components both in the background and in the user interface and ensure that websites run efficiently.

    Backend developers use their programming skills when creating the background of the website and create the business logic.

    They also manage databases and provide security measures. They optimise the functionality and performance of websites and ensure that users have an efficient experience.

    In order to perform this profession, it is necessary to receive training in software and develop technical skills. To become a backend developer,

    it is important to learn many programming languages and to be able to use them effectively. After having technical knowledge, position and training, you can work as a backend developer.

    Backend developers usually create and manage systems that run in the background of websites and applications. These systems are usually developed using a set of programming languages known as server-side scripting languages. Here are some of the programming languages commonly used by backend developers:

    Python: Python, a general purpose programming language, is very popular among backend developers. It is simple, readable and offers a wide library support. It can be used with web frameworks such as Django and Flask to develop fast and powerful web applications.

    JavaScript: Widely utilized in web development, JavaScript is a programming language. Thanks to the Node.js environment, it extends its applicability to the backend. Leveraging frameworks like Express.js and Nest.js, it facilitates the creation of dynamic, interactive web applications.

    Java: Primarily favored in extensive corporate endeavors, Java stands out for its reliability and high performance. Collaborating with frameworks like Spring and Jakarta EE, it empowers the development of intricate backend systems.

    Ruby: Ruby is a programming language that draws attention with its simple and understandable syntax. The Ruby on Rails framework provides an ideal platform for developing web applications quickly.

    PHP: PHP, which has long been used in web development, is ideal for dynamic content creation and database interaction. Frameworks such as Laravel and Symfony increase the power of PHP, enabling the development of modern and scalable web applications.

    C#: Developed by Microsoft, C# is often used in conjunction with the .NET framework. It is especially preferred for the development of Windows-based applications and large-scale web projects.

    Each of these languages offers different strengths and is preferred depending on the requirements of the project. Backend developers usually know a few of these languages and choose the one that suits the needs of the project.

    Backend developers use various database languages to interact with databases and store data for their websites and applications.

    Here are some database languages commonly used by backend developers:

    SQL (Structured Query Language): SQL is known as a standard query language used in relational database management systems (RDBMS). It is used to access, add, update, delete, and query databases. SQL is supported in almost all popular RDBMSs (e.g. MySQL, PostgreSQL, Oracle, SQL Server).

    MySQL: An open-source RDBMS frequently employed in web applications, MySQL is celebrated for its swift performance, dependability, and user-friendly nature. Supported by numerous hosting providers and boasting a vast community, it remains a stalwart choice in database management.

    PostgreSQL:PostgreSQL is an open-source and robust Relational Database Management System (RDBMS). It offers advanced data management features, support for a wide range of data types and complex query capabilities. It is especially preferred in large-scale and complex projects.

    MongoDB: MongoDB is a document-based NoSQL database. It stores JSON-like documents and works with JavaScript. It provides flexible data modelling, high performance and scalability. It is especially ideal for modern web applications running on JSON data.

    Redis: Redis is a key-value based NoSQL database. It is designed for fast access and high performance. It is frequently used as a cache, for session management and in scenarios such as sorting operations.

    SQLite: SQLite is a lightweight native database engine. It is easy to configure and is often used in native applications, embedded systems and small-scale web projects.

    Each of these database languages addresses different use cases and needs. Backend developers choose the right database language depending on the requirements and performance expectations of the project.
