Who is a Full-Stack Developer?
A Full-Stack developer is someone who knows both Front-End and Back-End. They usually don’t have very deep knowledge in both at the same time. In other words, they can handle general tasks very well, but if they need to build something very specialized, it can become challenging for them.
A Full-Stack developer is like a general doctor. They can do many things and check many parts, but they cannot do very specialized surgeries.
If you think about it, most of the time when we get sick, our problem is solved by a general doctor. In many cases, we don’t need a specialist. Programming is similar. Most projects can be done by a Full-Stack developer.
Who will be more successful in Full-Stack programming?
If you feel your personality matches both Front-End and Back-End, and you also have the traits below, you might be more successful as a Full-Stack developer:
- If it doesn’t bother you that sometimes you may fall behind in very technical or deep discussions
- If you prefer working alone rather than in a big team
- If jumping from one topic to another feels exciting to you
- If trying new things is enjoyable for you
- If you like reading general, simple books in different fields more than reading deep, specialized books in one topic
Advantages and disadvantages of being a Full-Stack developer
Most Full-Stack developers earn more money than a Front-End or Back-End developer, because they do both jobs.
But on the other hand, their chances of working in big companies are usually lower. Big companies prefer to work in a very specialized way. Their projects are complex, so they need people with deeper knowledge in each area. They also have enough budget to hire many developers.
Big companies usually have mature products and everything is already structured. But in small companies, things are still fresh and not fully defined, so you can be more creative. So if you don’t like routine work, becoming a Full-Stack developer might be better for you.
If you become a Full-Stack developer, you might work for small companies for many years. Many of these companies fail or their projects stop. This means after years of work, your résumé may not look very strong, because the places you worked at no longer exist or their projects failed. So your résumé might become weaker.
Full-Stack developers also face another problem when looking for jobs. They often want to apply for both Front-End and Back-End roles, because they have worked on both. They feel confident that they can pass the interviews. But when they look at job posts, they sometimes get disappointed, because many requirements listed there are things they don’t know.
Even if they pass the job post and get invited to the interview, they may still get rejected. After the interview, they sit and think: “Why did I get rejected? I have years of experience…”
But this is the reality. Full-Stack developers often struggle with this.
However, imagine a company wants to hire a CTO or a technical manager. Between a Front-End, Back-End, and Full-Stack developer, who is the best candidate?
My answer is: a Full-Stack developer.
Why? Because they understand the whole software development process much better than the other two.
How is the job market for Full-Stack developers?
To understand how big the Full-Stack job market is, you can simply visit job-search websites and search for the word “Full Stack.”
You will quickly see how many companies are looking for Full-Stack developers and how strong the demand is in this field.
How can you become a Full-Stack developer?
I have prepared a roadmap for you that includes everything you need to learn.
This roadmap is made with a focus on the job market, which means I included only the skills that are really necessary for getting your first Back-End job.
There are many other things you can learn in Back-End development, but this roadmap shows the most important and practical ones you need to start working and earning money.
Don’t become a Full-Stack developer if…
If you are at the beginning of your journey and you want to enter the job market, I don’t recommend trying to become a Full-Stack developer right away.
Becoming Full Stack should not be your goal from the start — it should happen naturally over time.
How does that happen?
For example, you may start working as a Back-End developer in a company, and then the team needs someone to help with Front-End tasks too. You learn it because the job requires it. After some time, you realize that you have taken steps toward becoming Full Stack.
My dear friends, you cannot learn both Front-End and Back-End at the same time and expect to be strong in both from day one. These skills must grow through real work experience.
So my suggestion is this:
If your job requires you to learn the “other side” (Front-End or Back-End), then it’s a good chance to learn it and become Full Stack.
But if it doesn’t come from real work needs, don’t force it.
