Python is a general purpose programming language that boasts an impressive library for data processing. For back-end development, Python brings the advantage of programmer productivity through its simple syntax and short code length. To understand the back end, or the “server side,” you also have to know the front end and how the two interact. The front end, also called “client-side” programming, is what happens in the browser—everything the end users see and interact with. The back end, on the other hand, happens on the server and databases.

• The front-end of a website is the part that users interact with.
• Back-end languages will differ in file size, performance, compatibility, how many lines of code required, and the style of programming.
• There are two types — Object-oriented programming languages such as Python, .NET, and Java, and functional programming languages such as Clojure, Haskell, Ruby On Rails, and SQL.
• It’s also important to fluidly partner with other teams across the business to understand specific goals, needs, and opportunities and then execute on those directives.
• However, the average base salary of a back-end developer is $117,868, plus a $4,000 cash bonus per year (Indeed.com).

Think of middleware as plumbing for your site—it pipes any communication, like requests and responses, back and forth between your application and your server/database. Just like plumbing in a house, you don’t see middleware, but it’s there and it has to be reliable and always do what’s expected of it. C++ combines all the features of C with object-oriented programming features such as classes. As a low-level programming language it is used to communicate efficiently with system hardware for better performance. This makes it ideal for video games, large web applications, and other use-cases where system-level performance is a premium.

That’s why back-end developers should learn about depth-first search and breadth-first search algorithms, sorting algorithms like the bubble sort, selection sort, insertion sort, merge sort, quicksort, iterative and recursive algorithms. Back-end development can be much more varied than front-end development, which is largely driven by JavaScript, HTML, CSS, and various front-end frameworks using these languages.

While traditionally considered a front-end scripting language, the introduction of Node.js showed the world that this general-purpose object-oriented programming language could also be used on the server-side of applications. As one of the core technologies of the web, JavaScript is now a popular choice for front-end and back-end web development. You can’t talk about the back-end portion of an application these days without touching on APIs and how they connect software, applications, databases, and services together seamlessly. APIs play an integral role in how most server-side software architectures are built, oftentimes replacing more complicated programming to allow software to communicate and data to be transferred. Middleware also lets cloud applications and on-premise applications “talk,” and provides services like data integration and error handling. Good middleware can also maximize IT efficiency and power things like user engagement, business process management, content management, authentication, and more.

Knowledge of caching mechanisms like varnish, Memcached, Redis is a plus. A full stack developer would be responsible for the entire flow of your experience with this blog post, from its load time and layout to its interactiveness and structural underpinnings. The back- end of a website consists of a server, an application, and a database. Everything you’re seeing on this website right now was made possible by a front-end developer. A designer created the logo and graphics, a photographer took the pictures, and a copywriter wrote the text.

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

The Learning Pathway

It’s the machinery that works behind the scenes—everything the end user doesn’t see or directly interact with, but that powers what’s happening. They act as a bridge between the back end and the databases and allows the developers to fetch the user data. Typically, most back-end developers work with Python and NodeJS to create the APIs. Once you’ve created your job post, kick off your search for top talent to invite to your project. Upwork has smart filters that let you drill down into the skills and categories you need.

Java is a general purpose object-oriented programming language that was designed with cross-platform compatibility in mind. Any machine running an installation of the Java Virtual Machine can execute Java programs. Let’s take a look at the different types of back-end programming languages. Using these tools, full stack developers need to be able to immediately identify the client- and server-side responsibilities of a solution and articulate the pros and cons of various solutions. The idea is that a full stack developer can work cross-functionally on the full “stack” of technology, i.e. both the front end and back end. Job openings for back-end developers often also call for experience with PHP frameworks like Zend, Symfony, and CakePHP; experience with version control software like SVN, CVS, or Git; and experience with Linux as a development and deployment system.

Other languages may be compiled rather than interpreted, something that affects load time, readability, and processing power required to run the application. Back-end development refers to the development of server-side logic that powers websites and apps from behind the scenes. It includes all the code needed to build out the database, server, and application. From database migrations to API integrations to setting up the server-side technologies that make a website tick, a back-end web developer may be the talent you need to get your next web project off the ground.

It contains behind-the-scene activities that occur when performing any action on a website. It can be an account login or making a purchase from an online store. Code written by back-end developers helps browsers to communicate with database information. Full stack developers work, like back-end devs, on the server side of web programming, but they can also fluently speak the front-end languages that control how content looks on a site’s user-facing side.

In addition, if you enroll in a Udacity course or nanodegree, the storage of your personal information—and the fact that each time you return to the site and log in, your data is called up—is attributable to a back-end developer. A back-end developer builds and maintains the technology that powers those components which, together, enable the user-facing side of the website to even exist in the first place. A lot of front-end developer job listings also call for experience with Ajax, a widely used technique for using Javascript that lets pages dynamically load by downloading server data in the background. Unlike technical questions, behavioral questions do not vary based on your experience level. Ultimately, the interviewer is trying to evaluate your working style to check whether you are the right fit for the company.

Developed by Larry Wall in the 1990s, Perl is a general purpose programming language that’s popular in the Linux and Unix world.
