A Complete Learning Path to Becoming a Backend Developer [2022 Updated]

By Lane Wagner on Jul 24, 2022

So you’ve decided that backend development is the career for you - congratulations! Many self-taught coders have a hard time deciding between all the various options, but it’s so much easier to learn effectively if you have a clear goal, like backend work, in mind.

Before we get started, if you want the “quick answer”, check out Boot.dev - it’s a platform I built from the ground up to teach you backend development completely online. If you’d rather do a deep dive on the kinds of things you need to learn, rather than get started with a specific learning platform, read on!

Below, we’ll cover everything you need to learn back-end development in 2022 from knowing basically nothing about programming to getting your first job as a Backend Developer. This article is a compilation of my own experience and expertise as a backend engineer and hiring manager, as well as other who’ve I’ve consulted with to ensure this can be the best guide it can be.

First, what is a backend developer?

Backend developers are just one of many kinds of “programmer”. Back-end developers build and maintain the systems that store, process, and secure the data used by websites and apps. This is in contrast to front-end developers, who control everything you see and interact with directly in your browser or on a mobile app. Backend developers concern themselves with servers , while front-end developers work on clients.

Some of the most common job titles for programmers include:

According to Stack Overflow’s last developer survey , backend developers in the US tie for the highest median salary of this group: $150,000. If you enjoy working on problems that involve algorithms, data structures, natural language processing, databases, or distributed systems, then backend development might be for you.

A simple path to your career in back-end development

The pace of Boot.dev's JavaScript, Python and Go courses has been perfect for me. The diverse community in Discord is a blast, and other members are quick to help out with detailed answers and explanations.

Can I really learn back-end by myself?

Many people assume that because backend developers typically need to have a better understanding of computer science fundamentals, that’s it’s harder to get an entry-level backend position, and as a result, they start educating themselves on front-end technologies. I think this is a mistake.

Just because CS skills are often a requirement for backend positions, it’s almost never the case that a CS degree is required. If you take the learning path I outline below, there’s no need to go back to university.

The Learning Path - How to Become a Backend Developer

Alright, now that we’ve answered som preliminary questions, lets get onto the learning path! I’ve

Follow these steps in order - there are plenty of places you can learn back-end online effectively, some of the resources are paid, some are free.

1. Learn basic coding skills

Learning simple coding syntax is actually super fun and it’s exciting when you get up and running almost immediately. Your goal at this juncture should be to understand the basic syntax of one or two programming languages. JavaScript and Python are great choices. You should be learning simple concepts like:

Basic coding skills are a prerequisite to everything else we’ll be learning on your path to a backend career.

2. Master data structures & algorithms

This step might take a bit longer - your goal here should be to learn computer science fundamentals . Go deep on some of the most common algorithms and data structures concepts. Backend interviews are often full of questions on this topic. As a backend developer, it will be your job to make sure that the companies servers are running code that’s fast and performant.

We haven’t really gotten to the meat of backend development yet, but that’s okay! We’re setting the stage and laying a great foundation so that once you get to the later steps you won’t be lost and confused.

3. Learn the basics of the web

Now that you understand basic coding fundamentals in at least 1 programming language, your goal should be to understand the client/server model. You should come out of this step being able to answer questions like:

Your goal here is to understand why we need backend developers at all, and how the internet works at a basic networking level. I’d recommend actually doing a couple small, simple front-end projects so that you can understand the role a backend server plays in an application.

4. Get started building simple web servers

Next, you need to pick a language or two that you want to specialize in. For example, I’m primarily a backend Go engineer - but I dabble in Python and JavaScript. By specializing, you will make your job search easier on yourself. Companies want experts in the areas they’re hiring for - not jack-of-all-trades. Here are some projects you can take a look at:

Learn about different backend technologies and concepts like:

Your goal should be to build very simple web servers that serve a purpose!! Try building an API that’s fun, something like the PokeAPI or maybe the backend of a wiki for your favorite TV show. I would recommend not getting started with databases quite yet! Use flat JSON files or just in-memory storage on your server code for now.

5. Learn database fundamentals

Almost every backend server in the world uses one or more databases to store information. The architecture of most web backends looks something like this.

I would recommend becoming familiar with a SQL database first, probably PostgresQL. After that, get familiar with some of the NoSQL options, but I don’t think you need to be an expert on all them. I’d recommend just being familiar with them from a high level so that in interviews you’re able to hold your own.

6. Deploy some projects to your professional portfolio

Finally, you’re going to want to actually deploy some projects! This is how you show employers as a self-taught dev that you know what you’re doing. Unlike a front-end developer, as a back-end developer it’s less about a beautiful personal website, and more about the code itself. In order of importance you should work on the following things:

Not only will deploying your projects make your online presence appear more attractive to potential employers, but it will give you practice that will be necessary in your jobs moving forward. What’s the use of a backend developer if they don’t know how to deploy their code to a live environment?

Get a back-end job without spending $10k on a bootcamp

I was a field service engineer and I wanted to become a backend developer, but work and family limited my options. Since completing the back-end career path on Boot.dev, I now have a job offer in hand and I'm starting my career as a software developer!

7. Start looking for a backend job

The big secret to landing a backend job as a self-taught developer is to build an amazing online presence that flaunts your work. Like we mentioned above:

Once you’ve done that start applying to jobs! Use every job board you can find, and try to apply only to jobs that are specific to your area of expertise - e.g. “backend go developers”. Try to find niche job boards if they exist, I really like the Golang cafe , for example.

Further learning

Most importantly, do not stop learning and building!!! I’ve seen so many developers think that they’ve successfully “learned to code”, and they shift gears entirely to their job search. Look, it only takes an hour or so each day to submit a bunch of job applications. You should be spending the rest of your free time continuing to build. The more you learn and build, the easier the job search gets.

My favorite backend programming languages

You can be a backend programmer in almost any programming language, but here are some of my favorites in descending order:

How long does it take to learn back-end development?

If you’re starting from zero, it will probably take you anywhere from 9 months to 2 years to learn back-end development thoroughly enough that you can land an entry-level position. Of course, it will be different for everyone, but if you can put in a good 10 hours each week, I think that’s a solid estimate. The good news is, that’s faster and cheaper than going back to university for 4 years. The hardest part is just sticking with it.

Good luck out there, I’m sure you’ll do great!
