Introduction
Every website you visit has a different way of working. One-click leads you to a different page, and you can contact the service provider in just a few simple steps. It all depends on the foundational code on which a website is built.
Back end development is all the coding that runs in the background to ensure the smooth functioning of a website.
From the user interface to accepting inputs, back end development ensures that each visitor has an optimal experience when they interact with their website. But back end development controls more than just the user interface and experience. Let us explore what back end developer jobs demand and how you can get them.
What Does A Backend Developer Do?
A back end developer focuses on the maintenance of systems so that the data processing and server functions work seamlessly. In addition, a back end developer is involved with the server functions and the software that ensure the website performs smoothly while establishing communication with databases. Working with storing and deleting data, a back end developer also works on the architecture and programming interface of the website.
In essence, back end developer jobs require someone who can create code that effectively communicates between the database of the website and the platform from which the end user is accessing the data. A lot of information needs processing before it becomes accessible to the front end.
The job of a back end developer is to employ back end logic to make the client experience easier by helping them with information relevant to their queries. For instance, if a user visits a shopping website or is directed to the product catalog page, they would require options to add items to the cart. Therefore, a back end developer ensures that relevant information like the number of items in the cart, the individual item, and the total price, along with shipping cost, is readily available to the user.
The role of the back end developer starts with creating, followed by maintenance. It also features debugging a website and application programming interface (API). The backend application logic and the databases of the service provider are always running in the background whenever there is interaction on the front end.
A back end developer is responsible for overseeing the following aspects of running a website:
- Storing and restoring user data so that it is available upon request.
- Integration of application programming interface
- Integration of cloud computing
- Working with mainstream back end programming frameworks and programming languages
- Data security and preventing any leaks
- Database management and maintenance
The user experience with the website should be error-free which is what a back end developer aims at.
What Are The Must-Have Skills For A Back End Developer?
The must-have skills for a back end developer start with being familiar with at least one programming language and also having a rudimentary knowledge of working with databases. The skills in back end developer jobs primarily focus on problem-solving and analytical thinking along with knowing the technical details of the job. Here are some must-have skills every aspiring back end developer should prepare themselves for:\
Creating the foundation
Building a website is the first prerequisite of any back end developer. Creating a website requires efficient use of frameworks and programming languages, which would create a prototype for a prospective website. A developer needs to have working knowledge of cross-platform functionality while designing a prototype to minimize the error margin when a user accesses it. Along with building a website, the back end developer should also possess the foresight to maintain their website through debugging and regular testing.
Quality testing
Checking for quality is mandatory whenever a new product or service is launched. Since user interface and experience are a priority while designing a website, quality assurance testing should focus on cross-platform compatibility and seamless display on all devices and browsers. In addition to compatibility, the programming code should also be clean and sustainable for easy future maintenance.
Response Time
Quality testing can also include assessing the response time of the website. Any user or potential client has no shortage of options when it comes to browsing the internet for information or services. The attention span of the average user is declining, which means that they expect results within seconds. A longer response time can cost a service provider valuable clientele in a scenario of extensive competition. Just because a website run does not mean it is ready for users. The scalability and efficiency need proper testing so that the users can get quick response time and optimal performance irrespective of their devices or browsers. Response time testing is also necessary after each patchwork or upgrade. The codes should be adaptable enough to accept adjustments regarding the speed of the website.
Troubleshooting
A back end developer is expected to work in a team or collaboration with clients or project heads. They require constant communication to provide the best results and troubleshoot errors as and when they arise. Troubleshooting is a must-have skill because it exists in tandem with communication so that the client or supervisor can ensure optimum performance. Even after the initial troubleshooting, a back end developer is expected to provide customer support and maintenance assistance. One might also be expected to train or mentor junior developers in a developer role.
Security functions
A back end developer also supervises the security of the website they create. Protecting the databases and servers from leaks and hacking attacks is also a part of their job. A website requires strong authentication controls so that only the right user can log in and have access to their personal information.
Technical skills work along with soft skills, especially while designing a website for a client. Good communication, practical action, and problem-solving can be constructive for aspiring back end developers.

What Are The Tools That Back End Developers Use?
The tools a back end developer makes use of include frameworks, version control, databases, servers, API design, and programming languages. Different back end developer jobs have different prerequisites from their applicants.
Therefore, depending on where you aim to apply, gaining more experience in the skills that an employer asks explicitly for is helpful. Some of the most frequently used tools for back end development are as follows:
Databases
Since the use of databases is crucial to back end development, a developer is expected to know how to work with them. MySQL and Oracle are very common databases used for the majority of websites. A database management system works to organize the data of the client. A back end developer should know how to request data and use it in the most efficient way possible. MySQL is a part of the SQL database systems. The SQL database system also includes PostgreSQL. While applying for back end developer jobs, you might also be expected to know the basics of using relational and non-relational databases.
Programming languages

Coding is the backbone of any website which is why any developer should have a decent command of them. The most commonly used programming languages in back end development are Python and JavaScript. While most employers would expect you to use these two programming languages, others might expect specialization in C#, Ruby, PHP, and Java.
It is important to note that JavaScript is used mainly for front end development, yet back end developers should have a basic knowledge of it. A back end developer can improve on their work when they know the workings of front end development as well. It is why working knowledge of CSS and HTML is also appreciated.
Web Hosting Platforms
Whenever a new website is in the development stage, one has to look for a host for it. While it may depend on the request of the client or the employer, one should know the most prevalent cloud service providers. Many hosting platforms offer both free and paid services. Microsoft Azure, Google Cloud Platform (GCP), and Amazon Web Services (AWP) are in high demand currently.
Frameworks
Frameworks are the most important of all back end technologies. A framework is an entire library on which you can base your program. Different frameworks work for different uses and can make the building process easier than starting everything from scratch. For better understanding, consider the framework a basic structure that requires a specific programming language for execution.
One can use the Django framework for the most commonly used programming language, Python. Similarly, when you decide to use Node.js, you will need to have a grip on JavaScript. However, it is crucial to note that different frameworks can use the same language. For instance, the Flask framework also uses Python. Some other frameworks you can explore are Ruby on Rails and Laravel.
The goal of any job is to be as efficient as possible. When you are working with algorithms and structure, it is helpful to know the compatibility and functionality of different tools. This is only feasible if you know how to use the tools required for the job.
