Backend/API development is the skill used by developers to power the internet. It enables people to get what they are looking for on the web.
It does this so well that a person does not have to care or know about the things happening in the background.
Multiple backend and API development languages are responsible for handling how applications work. They provide the code that powers web applications. They also manage connections between users and connect databases to the web.
What is Backend/API Development?
As discussed above, backend/API development keeps the web running. It does this without its users noticing the things happening in the background.
If you were to get a job as a backend developer, some of the things that you would be asked during an interview include how to test an API and the process of building one.
In addition, you should be good at writing clean code that works with databases and creating libraries among other things.
As a backend/API developer, your main job is to focus on how an application or a website works. The code you write should focus on the logic and usage of the application you are working on. It should not be based on how the application looks.
However, it should be clean and the usage of the application should be smooth. Users should not have difficulties using the application. They should find everything smooth and simple.
The technology used by these developers revolves around databases, applications, and servers. It is not seen by the users of the applications that they (the developers) work on.
Learning Backend/API Development
The first step into learning backend/API development is to understand what it is and what it entails. To be successful, you need to understand the two concepts of backend/API development. They include functional and object-oriented programming (OOP).
Functional Backend/API Development
Functional backend/API development is based on actions. It employs the use of declarative language. This means that you can execute your statements in any order that you choose to.
Some of the most popular programming languages here include R, F#, and SQL. It is popular with data science projects.
Object-oriented programming, on the other hand, allows developers to create objects. They, however, have to implement an order through which their statements should be executed.
Some of the most common programming languages with OOP include Python, .NET, and Java.
You also need to understand how to write dynamic or static code. Static code allows you to easily catch errors even though it is rigid. Dynamic code allows you to change the type of your variables, meaning that it is more flexible. After this, you can now;
Get into Algorithms and Data Structures
It is important to have a basic knowledge of algorithms and data structures. The most important things for you to learn here include algorithms and data structures searching and sorting. You will also need sorting, hashing, graph, tree, linked lists, queue, and stack.
Backend/API developers create solutions to make our everyday life easier. Algorithms and data structures help improve the ability of these developers to solve problems.
For instance, your programming task will be made easier by having the right tools for the task. However, you need to know how to properly use the tools and the right data structures when solving a problem. This minimises the risk of failures and improves resource usage and performance.
Get Good at Programming Language(s)
Learning backend/API development is going to take time, patience, and effort. You cannot learn different programming languages and frameworks within a day.
You can choose a programming language or two to start learning. The best languages to consider include Java, Python, PHP, and R among others.

This is because these languages are not only dynamic but also general-purpose. They come with dynamic binding/typing and pre-existing structures.
This reduces the cost of maintenance of applications. Their resource libraries and interpreters are available for free on the internet.
The next step that you need to take is learning the basics of working with a database. You can find multiple database management systems on the web, but make sure that you choose the one that you feel is good for you.
This is important because the technologies you will use include databases. In addition, almost every other application relies on a database, so this is important.
This will be dictated by the programming language that you choose to learn above. However, you need to make sure that you are good at at least one framework. Fortunately, most modern frameworks implement a similar MVC principle.
It will take you more time and effort to write the entire code on your own in a certain programming language. However, if you decide to use a framework, you can create code and templates that you can always use for other projects.
Work on a Project
Finally, you can now start working on a project to test yourself. Since you are just starting and testing yourself, look at something already available in the market and make a clone.
The secret is just practicing to achieve great performance. Build more applications, test yourself, and try to improve every day for you to be a genius in what you do.
If you succeed at this, then you are ready to go. You can now innovate and implement an idea that no one else has worked on. After that, look for a good hosting provider and show the whole world what you are capable of doing.
Backend/API developers are among the best-paid software developers in the world today. In addition, you will always find jobs to do, creating new solutions and building APIs and applications.
This gives you a chance to keep on learning new things. You need this because of the evolving nature of technology. You can decide to get employed or become a freelancer and still earn good money doing something that you love.
