Skills You Need to Become a Backend Developer โ A Roadmap for Beginners ๊ด๋ จ
In this guide, I'll discuss the basic skills you need and steps you can take to become a backend developer.
I'll give you a simple roadmap that'll help you know where you are and where you should go next.
Front End vs Back End
Every website has two parts: a front end and a back end.
The front end is the part that you see in the browser and interact with. Basically, it represents all the visual aspects of a website.
The back end is the part that powers the front end. It's behind the scenes, and it's mainly concerned with storing and accessing data using databases, APIs, and so on.
Because of this, web development jobs fall into three main categories:
- ๐จโ๐ป Front-end development
- ๐ Back-end development
- ๐ข Full-stack development (involves both front-end and back-end development)
๐ทโโ๏ธWhat Exactly Does a Backend Developer Do?
Backend developers are responsible for constructing the foundational systems that drive the functionality of applications that users engage with.
This includes various tasks such as designing the architecture, and then implementing and maintaining these critical systems.
Their responsibilities typically involve working with:
- ๐พ Databases, such as MySQL,
- โ๏ธ Frameworks, like Laravel or Ruby on Rails, and
- ๐งจ APIs (Application Programming Interfaces).
Backend devs ensure that the backend infrastructure operates seamlessly, enabling smooth interactions between the user interface and the underlying data and processes.
Here are some of the core responsibilities of a backend developer:
- Understanding the website's performance needs and goals
- Developing and managing APIs for the website
- Developing systems for secure data storage and processing (especially special use cases like payments)
- Writing code, testing it, maintaining it, and developing solutions to bugs
- Designing the site's architecture using established methodologies like Agile/Scrum and various frameworks
- Organizing the system logic effectively
- Providing solutions to address system-related issues and challenges
๐ฅท What You Need to Know to Become a Backend Developer
Becoming a proficient backend developer requires mastering various skills and technologies.
Below, I've outline a comprehensive roadmap to help you achieve this goal as quickly as possible.
Just keep in mind that everyone learns at a different pace, so it's hard to set a specific timeframe on how long this will take. Some might be able to get through it in six months or less, but others might take significantly more time.
Step 1: Foundations of Backend Development ๐๏ธ
- Understand the role and responsibilities of a back-end developer. Familiarize yourself with databases, frameworks, and APIs.
- Join a comprehensive course on databases. Learn about SQL and relational databases like MySQL. Practice creating and managing databases.
- Learn about server-side programming languages. Start with PHP or Python. Learn basic syntax, control structures, and data types.
Step 2: Advanced Backend Concepts ๐
- Deepen your understanding of databases. Explore NoSQL databases like MongoDB. Learn about data modeling and optimization.
- Master server-side programming languages. Dig deeper into PHP or Python. Learn about functions, classes, and object-oriented programming.
- Get hands-on projects with frameworks. Choose a popular framework like Laravel for PHP or Django for Python. Build simple applications to understand the model-view-controller (MVC) architecture.
Step 3: API Development and Integration ๐ ๏ธ
- Learn about APIs and their importance in backend development. Explore RESTful API design principles.
- Start building your own APIs. Use tools like
Postman
to test and debug API endpoints. Learn about different authentication methods as well as security. - Focus on API integration. Learn how to consume APIs in web and mobile applications. Practice integrating third-party APIs into your projects.
Step 4: Troubleshooting and Optimization ๐ฎ
- Master troubleshooting techniques. Learn how to diagnose and debug backend applications effectively.
- Jump into performance optimization techniques. Learn about lazy loading, caching, load balancing, and database indexing.
- Learn monitoring and analytics tools. Use tools like New Relic or Datadog to monitor application performance. Learn how to generate and analyze performance metrics.
Step 5: Cloud Infrastructure and Deployment ๐ฅ๏ธ
- Understand cloud computing concepts. Learn about popular cloud providers like AWS or Azure.
- Take a course on cloud services for backend development. Learn about serverless computing, containerization, and microservices.
- Practice deploying applications to the cloud. Learn about CI/CD pipelines and automated deployment strategies.
Step 6: Advanced Topics and Projects ๐
- Now you're ready to learn more advanced backend topics. Choose topics like message queues, event-driven architecture, and real-time communication.
- Work on a capstone project. Choose a challenging project that integrates various backend technologies and concepts.
- Finally, reflect on your learning journey. Review your projects and identify areas for improvement. Prepare for job interviews by practicing coding challenges.
Back-end Development Tools and Software
Here's a breakdown of the tools and software commonly used in back-end development:
1. Database Frameworks:
- MySQL: A relational database management system used for storing and retrieving data. It's widely used for web applications and offers scalability and reliability.
- MongoDB: A NoSQL database program that uses JSON-like documents with schema flexibility. It's suitable for applications with rapidly changing data models or unstructured data.
2. Web Servers:
- Node.js: Node.js is a cross-platform (meaning it supports multiple operating systems) JavaScript Runtime Environment that uses an event-driven, non-blocking I/O model. That means it can handle a large number of users at the same time. If you already know JavaScript, Node.js will likely be your best choice for building real-time applications like chat apps, online gaming apps, and collaborative tools.
- Apache HTTP Server 2: An open-source web server software that delivers web content across the internet. It's known for its stability, security, and flexibility, making it a popular choice for hosting websites and web applications.
If your team is used to using languages like PHP or Python, Apache might be easier for them to work with. - LiteSpeed: LiteSpeed is another web server software that helps websites handle lots of visitors without slowing down or crashing. Itโs great for businesses that expect a lot of traffic, like during busy times. LiteSpeed also works with many programming languages like Python, Ruby, PHP, and Java.
Imagine you're a company with 20 servers that can each handle 500 websites. Together, thatโs 10,000 websites. But if you switch to LiteSpeed, you might be able to handle 20,000 websites with the same number of servers. Thatโs a big improvement!
When choosing a web server, it depends on what kind of website or app youโre building. If youโre just starting out, try Node.js first. Itโs simple because you only need to learn one language (JavaScript) to build both the front part and the back part of your website.
3. Security Protocols:
- SSL/TLS Certificates: These are cryptographic protocols that provide secure communication over a computer network. SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) encrypt data between the server and client, ensuring confidentiality and integrity in online connections.
4. Version Control System:
Next on your journey is to become familiar with version control systems. These systems help track project history and enable collaborative work with others.
- ๐ Learn Git: Git is the most widely used version control system, employed by over 70% of software development teams. It's a must-know tool, and allocating around two weeks for learning Git is advisable.
Back-end developers usually utilize these tools and software to build robust, scalable, and secure web applications that handle data storage, server hosting, and encryption of online communications.
