That means you’ll be able to apply for both software engineering jobs and web development jobs alike—or land a gig doing both.

Ready? This guide will help you plan a full stack web developer career roadmap, point you toward the web development skills you need, and land the job—in as few as 90 days. Here’s how to do it.

Our 7-Step Method to Become a Full Stack Developer

1. Get to Know What Full Stack Means

Before you jump into the learning the skills, let’s get clear on what a full stack developer actually is.

Full stack developers are developers who work with both the front and back end of a website or application. They’re familiar with HTML, CSS, JavaScript, and one or more back end languages. Hence the term “full stack”—they’ve got all the web development skills to build sites and apps from start to finish.

Here are some other common questions about full stack (just to get this out of the way!) before we dive into our 90-day plan:

Is a full stack developer different than a software engineer?

Yes and no. The title “full stack developer” describes a programmer who’s qualified to work on both the “front end” (stuff users see on their screen) and “back end” (the stuff behind the scenes) of websites and mobile applications (a type of software). This means full stack developers working on apps can also be considered software engineers.

The title “software engineer” itself simply describes a programmer who works on some aspect of building a software program, meaning not all software engineers are full stack.

What’s the difference between a full stack developer and full stack engineer?

This one’s easy! Full stack developers are web or app developers who can work on all parts (front end and back end) of a web development project. Full stack engineers are usually more senior full stack roles that combine development know-how with skills like project management and DevOps.

What’s a full stack developer salary? Is it more than a regular web developer?

As of this writing, Indeed cites average full stack developer salaries at $109,508 per year. That’s compared to only $71,130 per year for web developers in general. So yes, like most things tech-related, having more skills (being able to work on all aspects of a development project) means being able to pay more bills.

I heard it’s a bad idea to try to become a full stack web developer. True or false?

This debate rages on. Within the web development community, depending on who you ask, you’ll get two very different answers.

At Skillcrush, we tend to recommend that someone new to tech start by focusing—usually on front end web development—rather than try to learn all the full stack skills at once. From our experience, it’s very hard to put the time into learning tech skills if you’re bouncing around between too many lessons.

Still, there’s a reason why full stack developer salaries are so lucrative. And some of us really love to keep adding skills to our arsenals. So maybe the better question is: Is full stack development right for you?

2. Decide Whether Full Stack Web Development is Right for You

You may have heard whisperings that full stack developers aren’t necessarily beloved. There’s a pretty large divide between people who think of full stack developers as the famed unicorns of the tech world and those who feel like they’re spreading themselves too thin. Here’s a quick breakdown of the pros and cons of full stack.

Pros of Going Full Stack

  • Can work more easily on small teams or tech startups where there are fewer developer jobs to go around
  • Full stack developers know how to communicate with both front end developers and back end developers, helping cut down on lots of confusion
  • They can solve all problems at once—not just surface-level development needs

Cons

  • The biggest argument against full stack (we think) is this: If you’re not specialized, is the quality of your code ever going to be as good as it could be?
  • It’s hard to prioritize projects
  • You may find that companies that hire you for both front end and back end development expect you to do more work than you can complete in a 40-hour workweek (i.e. the cutting corners approach to a web development budget

3. Find Your Front End and Back End Web Development Skills Gaps

If you don’t have any web development skills, start by learning the ones that will land you a front end developer job. They are:

Essential Front End Developer Skills

Programming Languages Front End Developers Need to Know

If you’re already well-versed in front end web development and are determined to go full stack, these are the back end developer skills you’ll want to start learning next.

Essential Back End Developer Skills

  • API architectures (REST/SOAP)
  • Database management
  • General understanding of front end technologies (for cross-team communication)

Programming Languages Back End Developers Need to Know

P.S. Did you know we teach back end web development, too?

4. Teach Yourself the Necessary Programming Languages and Web Development Skills

Now that you know which skills you need to learn, it’s time to set about learning them—ideally within the next 90 days.

That may sound very little time, but here’s the beauty of becoming a full stack developer (or becoming any sort of web developer or engineer, really): You can start applying for jobs before you’ve finished learning all the skills. In fact, you can even find your first client as soon as you enroll in a web development course by using them as your class project.

Our Skillcrush courses are set up so that learning the skills you need can happen in 90 days or less if you study 1 HOUR A DAY. That means you could have a new full stack developer job before this season’s over.

Here are some of the best places to learn the necessary full stack skills:

Free Front End and Back End Web Development Courses

If you want to launch a full stack career in 90 days, investing in a high-quality course is worth it. But if you’re still not sure whether you even want to become a full stack engineer, you can start by trying out some free courses and resources. Here are just a few:

5. Build Up a Web Development Portfolio

Every web developer and engineer—front end, back end, full stack, haystack (heh.)—needs an online portfolio that showcases their work. Ideally, that portfolio is also one of your designs. Regardless, make sure to update it before you start applying with your strongest projects. If you’re new to learning front end development and/or back end development, you can add mock projects to your portfolio based on the work you’re doing in your courses. All good code—whether for clients or fun—counts.

7. Ace Your Web Developer Interview

Regardless of whether you’re attempting to land clients as a freelance full stack developer or you’re seeking full-time a full stack developer job, there are some best practices when it comes to interviewing.

1. Come prepared to answer technical job interview questions

Technical job interview questions function slightly differently than some of the interview questions you may have answered in the past. The best way to prepare for them is to practice via mock interviews. Here’s a list of technical questions to get you started, as well as some of the most common front end development interview questions.

2. Even if your goal is a full stack web developer job, come prepared to talk about your specialties

Yes, the beauty of full stack developers is that they can handle so many elements of the development process. But everyone has her strengths, interests, and specialties.

Chances are your interviewer will ask you whether you prefer front end web development or back end development. Don’t be afraid to share with them your favorite elements about both sides of the role, and how you particularly excel in one versus the other.

3. Bring a laptop or iPad to show off your portfolio

When it comes to landing web development jobs, your portfolio is essential—possibly more so than even your resume. Make sure yours includes clear examples of both your back end web development/engineering work as well as your front end development experience. (Here are some of the best web developer portfolios for inspiration and our guide to creating an online portfolio as well.)

4. Expect a whiteboard and/or custom project

Though not as common these days, there are still companies that will ask you to whiteboard during your interview to show just how well you know how to code. Make sure you’re prepared for that (here are some of our best tips on whiteboarding).

Also likely if you advance to the final interview round: a custom project. Make sure you dedicate time and energy to completing it including checking your work right down to the spelling and grammar of your submission (yes, even if you’re not a writer)
