IntroductionIn web development, there are three kinds of programmers. They are back end developers, front end developers, and full stacks, who can do both. If you are reading this tutorial, you’re probably interested in the back end of a website. Good for you because you will soon know what is a back end developer and how to start the journey to become one.
Back end developer responsibilitiesHopefully, you now know a bit about what is a back end developer and how his job is different from what front end people do. But what is a back end developer responsible for?
Server-side logicThe best way to answer when asked, “What is a back end developer?” is to say that it’s a developer who’s responsible for programming the actions the website performs on the server side. Your bread and butter will be:
- User authentication. Making sure that user’s account details are correct, that he has necessary permission to see what he’s about to see, etc.
- Order handling. How an order you make on the website is processed to make sure that there aren’t any mistakes.
- Optimization. Making sure that every piece of functionality the website has not only works but does it in the fastest way possible.
Automatic notificationsIt’s said that if you have to do a task repeatedly, you should find a way to automate it. This couldn’t be more true for website development and precisely one of the ways to answer the question What is a back end developer responsible for?
Data ValidationAside from coding the server side logic, another answer to the “What is a back end developer” question could also be: the guy who secures the system. The part of the website you see on the front end can be changed in the browser by editing the HTML and CSS you see when inspecting (F12 on Google Chrome). These changes last until you reload the page. If the whole website was this easy to change, banking online and even BitDegree would be impossible and extremely vulnerable to hacking attempts. Thankfully, that’s not how it works or the whole world would be in trouble. All the data you can imagine a website needs is stored in databases. When your browser generates the page you’re going to see, it calls the data values it needs, like prices, number of items in stock, etc., from a database. When you enter information, a proposal to update the database is made. What is a back end developer? The poor guy who has to create the processes which make sure that the data entered is valid before making server-side adjustments. The simplest case to show you how the process works is a simple login procedure.[email protected] with the password: $uPer$eurr£a$$512.
When you click login, this action triggers a request to see if there’s an account with the email of [email protected] If there isn’t you get a notification that the login details you entered are incorrect. If there is an account with that email address but the password recorded doesn’t match what you entered, you also get an error. To put it simply, any information you enter on the website has to be validated by the code written by a back end developer before it can become a part of the database.
Database AccessWhile it’s similar to the previous point, it’s worth splitting it off. As a back end developer, it’s your job to access the various databases maintained by the website to make the system do what it’s supposed to. You and your code is the critical point of failure in making sure that the website remains secure and works as intended. Also, it’s your responsibility to streamline the process of accessing databases in such a way that the website loads as fast as possible and its functionality is carried out as quickly as possible as well.
APIsSome people need third-party APIs to work properly. What is a back end developer? The lucky guy who gets to make sure everything’s alright! You might get to write the API for other websites to use your site’s functionality too. Working with and creating APIs could be a big part of your job as a backend web developer, so it’s a great idea to get comfortable with them. Fortunately, they can be mind-blowingly fun to work with because they save you loads of time. Or a splitting headache when you have to code a complicated system from scratch. Sometimes, however, APIs can be annoying and difficult to work with because of the decisions made by the people who coded them.
Better be good, son!
The Tools You Need for Back End DevelopmentOn your way to figuring out what is a back end developer, it’s great to know everything we’ve discussed above. You need to know what back end developers are and are not responsible for, what the job involves.
Okay, but how much can I make?The back end web developer salary question is very important when making a future career decision. It shouldn’t be, though.
What is a back end developer? A guy who makes Internet stuff work on the server side. The answer isn’t and should never be something like, “The guy who makes the big bucks!” No matter how much you get paid, it will all be worthless if it’s a slog to get through the day. Before you consider the back end developer salary factor, figure out if back end coding is even something you would enjoy doing. Making the server-side logic of a huge website work, securing back end operations, working with APIs and being responsible for the integrity of your databases are extremely important duties. Obviously, carrying this responsibility has to be reflected in the back end web developer salary you are offered. On the other hand, don’t expect to make a fortune as a Junior developer. At this stage of your career, you still have a lot to learn before you can be trusted with the responsibility, which brings in the generous compensation packages. In the parent field of web development, the back end development salary is the highest overall. You can expect to make upwards of $100,000 a year in New York City, for example. In other countries and cities, this figure may be quite a bit lower but then again, the cost of living in these places is appropriately lower in most cases. The back end developer salary also varies by country. In some lower average income countries, the back end developer salary you can expect is significantly lower than the New York City figure but still amazing when you take into account the national average. It’s almost guaranteed that you will pay the bills and have plenty left over if you make it in back end web development. With that said, remember that back end development and programming overall is a tool to solve a problem and build things. Don’t pursue this career for a paycheck, do it because you love it. Build things, solve problems, be happy. Don’t do what you hate for a fat paycheck.
