What is a Backend Developer?
A backend developer is a programmer who develops the server-side functionality of a website or application. This includes developing, maintaining, and testing the back-end components of systems such as servers, databases, and application logic. Backend developers collaborate with frontend developers, who build the visible components of a website or application.
While the front-end is what visitors view and interact with, the backend contains the majority of a website's or app's key functionality. The backend is in charge of storing and organizing data, as well as ensuring that everything on the client side (frontend) functions properly. It is a system component that users do not directly engage with but which powers the features they do interface with.
What does a Backend Developer do?
As the developer of the application or website's backbone, a backend developer performs duties that are invisible to the user, but are vital for a working application or website. Examples of these duties include:
- Design and Implementation: The core computational logic that enables a website or an application to run involves an array of tasks like managing user inputs, performing calculations, processing server-side logic, manipulating data, and more.
- Database Management: It is the job of a backend developer to create a database and manage it properly to fulfill the user's requests like storage, retrieval, and modification of its data. A backend developer is a database language expert, SQL or NoSQL.
- Server Integration: Making sure the server, application, and database can communicate with each other can be the more complicated work of a backend developer and is incredibly important for facilitating communication and data flow across their entire system.
- Testing and Debugging: Backend developers regularly test the application/website - looking for and fixing bugs and issues with their server-side logic to maintain optimal efficiency of their system(s).
- Security Measures: Backend developers practice security to protect the system and its data. Practicing security can include: encrypting information, managing user authorization, following secure server deployment best practices, maintaining integrity for passwords, and other security best practices.
- Performance Optimization: Backend developers want to optimize the performance of their backend functionality to make sure the backend functionality does what it is expected to do in an efficient and successful way.
- APIs Creation and Management: Back-end developers generally build APIs (Application Programming Interfaces) or leverage the existing ones to allow software components to communicate.
- Collaboration: They work closely with front-end developers to integrate front-end (user-facing) components with the back-end structure of the application.
In sum, the back-end developer maintains the behind-the-scenes function of components, to provide the interaction needed for the front-end components, which the user experiences directly.
Backend Developer Skills
Back-end developers have the technical skills to make web technology operate smoothly. They will develop applications with back-end logic by using server-side languages like Python or Java. They can also use front-end technologies to allow for integration of server-side functionality to the user interfaces.
When they work with databases, they will generally use MySQL or PostgreSQL as the database management system. They will be familiar with data management techniques to create, store, and retrieve data efficiently. They may also will use frameworks such as Django or Rails, to speed up the process of web development, along with the backend structure while using that framework. They may utilize Git to manage versioning changes and collaborate with other developers.
They can plan, develop and manage RESTful APIs to allow software components to communicate. Finally, they can deploy servers to the cloud and maintain their server while managing and deploying applications so they are available for the end user.
How to Become Backend Developer: A Step by Step Guide
To become a backend developer, you need to develop the right combination of technical skills, knowledge, and experience.These are the steps you could take to become a backend developer:
1. Learn programming languages
It is important to learn the programming languages that are typically used in backend development. Examples are Python, Java, Ruby, or Node.js. Begin with one language and become proficient in it.
2. Understand databases
Learn about databases, especially relational databases, and be able to design and manipulate a database’s tables. Also, be able to write some basic queries, as well as knowledge of normalisation, indexing, etc.
3. Study server-side frameworks
Look at server-side frameworks that are relevant to the programming language you have chosen. This could also be reading into frameworks like: Django or Flask (for Python), Laravel (for PHP) or Ruby on Rails (for Ruby). Frameworks can provide tools and libraries to aid development for backend development.
4. Familiarise yourself with API
Understand how APIs (Application Programming Interfaces) work. I would suggest reading about RESTful APIs and how to build them and consume them. APIs are important for components in a web application to communicate and provide functionality.
5. Learn about web servers
Becoming familiar with web servers such as Nginx or Apache is a good next step. Understanding the way they accept requests, serve static files and interface with your backend application is important as a backend developer.
6. Gain knowledge of version control
Familiarizing yourself with version control systems is also critical to becoming a good backend developer and is something that you may want to learn further along in your journey as well. For example, you may want to understand how to create a repository, create branches, merge branches, etc., and ideally collaborate with other developers on a single code base is an important process that you may want to prepare for.
7. Practice problem-solving
If you aren’t already a good problem solver, then working on becoming a better problem solver will be an enormous help as you become a backend developer. Backend development often requires complex solutions, so whether you practice special types of problem-based exercises or competitive coding and coding competitions (e.g., LeetCode, HackerRank) is really up to you. There are many different types of programming challenges online in order to practice.
8. Build projects
Once you understand the greater part of the backend fundamentals, I suggest starting to build some smaller projects on your own for some practical experience. You can try starting off with smaller application buildings and work your way to learning more complex applications. Building projects is one of the more beneficial aspects to embracing the career path of backend development.
9. Collaborate with others
Look to have conversations, code with coding communities, forums or find somewhere online to collaborate with other developers. Doing development with other people is a great way to learn about new techniques, gather insights and gather feedback on your code.
10. Continuous learning
Stay conscious of the field of backend development because it appears to be constantly evolving. Do your best to stay on top of the new technology, frameworks and best practices as they come out by utilizing online resources (i.e. reading blogs, tutorials, courses, webinars or following influencers in the backend development field).
11. Gain practical experience
Apply for internships, or entry level jobs, or freelance gigs to get some practical backend development experience. The experience of working on a real project will be helpful in sharpening your skills, and give you some exposure to the development process.
The journey to becoming a successful backend developer takes time, commitment, and work but don’t lose motivation! Continue practicing, learning, and using your skills, and you will eventually get better!
