Front-End Developer Job Profile

What Is the Salary of a Front-End Developer?

The average salary for front-end developers in Germany is about €45,000 gross per year. Developers with more experience — senior front-end developers — earn on average about €49,500 per year gross. The salary increases fairly linearly with work experience. For freelance developers who focus on the front end, the hourly rate is around €70.

As with most IT roles, there is no single blanket answer. The salary for front-end developers depends heavily on:

• The location
• The company
• The technical knowledge
• The work experience

As a rule, the larger the company the front-end developer works for, the higher the salary will be. In cities like Frankfurt or Munich, front-end developers tend to earn more than in other German cities.

What Is Front-End Development?

The front end describes everything that the user of a software or website can see and interact with. Another term for it is the “presentation layer”. Front-end developers develop dynamic applications — websites, software, and apps — with a focus on the user experience: designing and creating user-friendly interfaces. This includes design, menus, posts, pages, media, comments, and navigation through the corresponding interface. The next step is to review and test the features, for which front-end development also works closely with back-end developers.

A well-built front end includes several key qualities:

Clean Code Clean code makes it easier to prevent errors and gives other developers a quicker and easier overview of the project structure and logic.

A Good Performance Loading times are an important part of the user experience. If they are too long, they lead to a higher bounce rate and less interest in the website. For this reason, the media used should be compressed as much as possible and the number of server calls kept as low as possible.

A Good Design on All Devices and Screens Through Responsive Design, the interface can be adapted for all types of devices and screens. While an application may look coherent on a desktop screen, it may not look coherent on a smartphone.

Structured Data and Easy Navigation The interface should follow a sensible structure. Easy-to-understand navigation and a good overview are essential for a credible presentation. A so-called breadcrumb navigation allows the user to be guided through the application in small, easy-to-understand steps.

Social Media Details and Contact Information It is important that users have the possibility to find you on social networks or at least have a phone number. This way you can generate more traffic and draw attention to the website.

Internal Links Internal links are links to related topics on your website. They help the user to follow up on related topics and contribute to better search engine optimisation. This way the website can be found more easily on Google.

What Is the Difference Between Front-End and Back-End?

While the front end focuses on the visual level of a software — ensuring menus work, the application opens correctly, and interactions feel smooth — the back end handles the logic, data, and server-side processing that powers it all.

Example: If you upload private photo albums to a cloud service, the front end is everything you can see: the user interface, clickable buttons, image previews. The back end is the server that stores the photos, handles authentication, and manages the database that organises your albums.

What Are Front-End Languages?

Front-end programming languages are the tools developers use to design clear and descriptive user interfaces. The most important ones are:

HTML In itself, HTML is not a programming language — it is used to structure code and define the content and layout of a web page. It is the foundation of every website.

JavaScript JavaScript is probably the best-known programming language and is used for almost all areas of front-end development. A “client-side” model is used for JavaScript, which reduces the load on the server and thus significantly improves the speed and loading time of a website. Even more well-known applications, such as Netflix, run on JavaScript.

React React works within JavaScript and is designed to improve the user experience. It is actually an open JavaScript library developed by Facebook. Because of the great variety of features that serve to improve the user experience, React.JS became one of the most well-known and widely used libraries in the world.

Swift Swift is a programming language developed by Apple. For this reason, it is used for many applications that support Apple’s operating systems — iOS, iPadOS, and macOS. Swift has also supported Windows since 2020.

Angular Angular is also not a real programming language, but a tool for creating interactive applications and dynamic content. Especially for applications with a “feed” layout, Angular is becoming increasingly popular.

CSS CSS means Cascading Style Sheets. CSS is used to design websites and together with HTML it is one of the most widely used tools for this purpose. CSS can be used to specify design aspects such as font size, font colour, and other visual features.

TypeScript TypeScript is a variant of JavaScript. The name comes from the fact that every variable is given a type. Function parameters and outputs are also typed. TypeScript especially helps to avoid errors and also offers autocompletion, which makes programming easier.
