By 2012, the term “full-stack developer” began to appear in job descriptions and blog posts. Companies soon discovered that hiring developers with only one language was no longer profitable. Therefore, hiring a full stack web developer who can solve various tasks was much more useful and was starting to become the new norm.
There are two very contradictory misconceptions when it comes to defining what a full-stack developer is. These are:
- A full stack developer knows everything, so our company will save on human resources by hiring them.
- A full stack developer knows a little bit of everything but nothing too specific. A full-stack engineer will only be a burden to our team and will never be able to get into the details the way a frontend or backend developer would.
None of these statements are right or wrong. A full-stack developer is not a wizard who can replace the backend developers and frontend specialists — no. While a full-stack engineer must understand both worlds, their role is to help bring the two groups together. In essence, if you hire a full-stack developer, they’ll be like a bass player in a rock band.
These days, a software development team resembles a rock band. It’s ideal when you have backend and frontend developers covering their respective ends of the spectrum. If the project is well defined, both sides do what they do best, caring little about how the other side does it.
However, as we all know, very few things work perfectly in life. Developers spend most of their time figuring out misunderstandings. They do this during lengthy meetings. If you’ve ever attended such meetings, you know how little respect a frontend specialist will show for detailed suggestions to speed up the backend. That’s the reality. Often, the vision between both sides deviates.
This is where introducing a full stack programmer to your team can be a huge boost in the productivity of your team and project. A full-stack developer can understand the problems on both sides and translate them into code. This is one of those cases where having a full-stack engineer on your team can make a huge difference.
In this article, we will discuss aspects of how to hire a full stack developer. So, if you are planning to hire the best full stack developers for your project, this article will be beneficial.
Overview of Full-Stack Development
There are many areas in software development, such as front-end, back-end, mobile development, web and mobile app testing, and so on. Full stack developers are highly skilled in the world of web, application, and software development. Best full-stack developers are all-rounders in the programming world. They can juggle multiple technical tasks, which means a complete software development stack: frontend development, backend development, database, APIs, and Version Control Systems.
Growth of the Full-Stack Development Usage
According to Indeed research, demand for full-stack developers in the US grew by 206% from 2015 to 2018. In LinkedIn’s 2020 Emerging Jobs Report, full-stack developer jobs ranked 4th with an annual growth rate of 35% since 2015.
The Bureau of Labor Statistics forecasts an 8% growth of vacancies for web developers and a 22% growth for software developers from 2019 to 2029. Statista in its turn reports web development as the most in-demand tech skill worldwide:
As of now, the ability to create and maintain a system from beginning to end, or from interface to backend, is highly valued.
Therefore, we can confidently say that full stack developers are in high demand in the labor market. Besides, a 2022 Stack Overflow study of 61,000 engineers globally found that 46.82% identified as full stack.
Why Is Full-Stack Development So Popular and Important?
During contemporary times, full-stack developers often work with much larger and more complex websites and technologies than in the past. While one person can’t always do everything, companies benefit from hiring candidates who understand full stack. Many companies are looking for developers who can work in different areas and perform multiple roles instead of finding and hiring a few niche professionals. This is more cost-effective and allows one person to manage and understand each part of the project, thereby avoiding misunderstandings and division of knowledge.
Advantages and Challenges of Full-Stack Development for Businesses
Full Stack Development Advantages
Hire Full-Stack Developers to Improve Scalability
One of the first business benefits is the ability of full-stack engineers to work at different levels of the software architecture. This makes it easier for clients to build and scale a team of developers for their software development projects. Above all, full-stack developers are used to working in various environments. Consequently, companies that hire full-stack developers should, theoretically, be well-adapted to the ever-changing technology landscape.
All-Round Knowledge of Front-End, Back-End, and Database
Full-stack developers are well versed in the technologies used in client and server-side development, particularly front-end, back-end, and database. This means they can handle the development and testing of, for example, an MVP and later extend it to the final software product.
Hire Full-Stack Developers to Reduce Communication Delays
Hiring a full-stack developer implies that fewer developers will be needed for a project. Accordingly, working with fewer people allows for effective communication with fewer delays and misunderstandings. In addition, when a full stack developer works on a feature implementation, they are often responsible for the entire process, leading to more consistency in collaboration.
Hire Full-Stack Developers to Save Money
Hiring a full stack developer is the most effective option for businesses with limited budgets who are in search of a reliable and secure solution. This is because full stack programmers can perform many functions.
Faster Time to Market
Another benefit of full-featured development is that it can help businesses launch products faster. This is useful for businesses operating in a competitive market as it allows them to launch their products faster than competitors.
Full Stack Development Challenges
It’s difficult to evaluate full-stack developers: Recruiters often look at full-stack evaluation in a narrow sense, even though fullstack developers often have specialized front-end or back-end skills, as well as familiarity with other components of app creation. Once your goal is to hire the right full stack developers, it may require creating individual assessments for the same role, depending on the candidate’s skills and project requirements.
Each project has a different technology stack, so evaluating a full-stack developer requires a high customization level. For example, a full-stack Python developer may sometimes require Django + MySQL, Flask + PostgreSQL, or Django + MongoDB, depending on the framework and database organization.
Unrealistic expectations about hiring a full-stack developer: Suppose, a recruiter hires a candidate thinking they can do everything. In that case, the developer may not be suited for the given responsibilities. Conversely, you may inflate expectations for specific technologies, screening out qualified full-stack engineers who may turn out to be weaker in non-primary technologies. That’s why you need to know precisely what skills are required, develop an accurate job description, and tune the interview process.
Slows down the process: Hiring a full-stack developer affects the speed of application development because they won’t work as fast as specialized developers who focus on a single task.
When Should You Hire Full-Stack Development Services?
- When the company is relatively new or small: Full-stack programmers with good experience and knowledge can help a newer or small company grow quickly. They can create solutions from the ground up and place all the application components where needed, thereby creating a basic project architecture.
- When you need a technical lead: You, as an IT business owner, usually need someone who has extensive knowledge in development, makes sure everything runs smoothly and keeps all elements of the application together. Therefore, an experienced full-stack developer can easily take on the technical leader role.
- When the company wants to build an MVP: A minimum viable product (MVP) is a version of a product, consisting of only the most essential features. Before creating a full application, it is always a good idea to create an MVP to see if the application works the way you expect. By doing so, you can gradually increase the value of the project while eliminating flaws. Once the company launches the MVP, it will receive feedback from users on what’s missing from the app. Based on this, the company can add those features to subsequent versions of the app. Full-stack developers will prove to be the right choice in terms of cost and timeliness when a company intends to create an MVP.
- When constrained by cost: If your budget is limited, hire a full stack developer. In general, the cost of hiring one front-end and back-end developer can be almost 40% higher than hiring one developer with expertise in both areas. However, you must never compromise on quality and choose the best developers offering full-stack services.
What is a Full Stack Developer?
Full stack development can be divided into two main components: front-end and back-end development.
Front-End (client): It is everything a site or application user sees and interacts with.
Back-End (server): It is responsible for the logic and processing of user interaction in the application, i.e., user requests, and works with the database and API for transferring data. In a nutshell, this is the “brain” of the application.
Together, these two components make up the skill set of a full-stack developer. However, being a full-stack developer does not mean that the programmer has mastered everything required to work with the front-end or back-end. Instead, it means that the developer can work on both sides and understand what happens when building an application.
Types Of Full-Stack Developers
There are different types of software developers, but there are also different types of full-stack developers. Below, you can learn more about the main types of full-stack developers.
LAMP is the old classic industry standard for time-tested web development stacks. LAMP includes Linux (operating system), Apache (HTTP server), MySQL (relational database management), and PHP (programming language). This stack works effectively on all operating systems. When developing websites, it provides the best performance, cost-effectiveness, and flexibility. In addition, its components can be swapped or modified within a single stack.
LEMP stack is a collection of Linux OS, Nginx (pronounced ‘Engine X’) Server, MySQL (database), and PHP (programming language). Like Apache’s work in the LAMP stack, Nginx does for the LEMP stack, processing the user requests and responding with suitable output.
Django Stack developer uses the Python stack, which consists of Django, MySQL, HTML, CSS, and Bootstrap. Django is a free, open-source Python framework used for server-side web apps.
Ruby on Rails (RoR) stack
What Does a Full-Stack Developer Do?
The day-to-day responsibilities expected from a full-stack developer will vary depending on the project and the experience of the developer. However, looking at job postings for full-stack developers, you’ll notice that many positions share some core responsibilities. These include:
- Creation of front-end and back-end architecture
- Implementation and management of projects by applying certain programming languages
- Testing and debugging i.e., bug fixing
- Work with databases, cloud storage, and network resources
- API design and development
- Monitoring of web applications and infrastructure performance
Essential Skills for a Full-Stack Developer
A combination of certain skills is required to properly fulfill full-stack developer duties.
1. Front-End Skills
Front-end skills are quite similar for all full-stack developers. These include:
- Libraries, such as jQuery, React.js, and Backbone.js
- SASS metalanguage and LESS stylesheet language
- Frameworks, such as Angular.js/Angular, Vue.js, and Bootstrap
- DOM, AJAX, JSON technologies
2. Back-End Skills
To be considered a full-stack developer, a specialist should have a general scope of front-end skills and be able to work with the back end. The back-end language is not that important, instead, it is the platform that matters. For instance, it is important to distinguish the Java platform from the Java language. The Java platform can use different programming languages i.e., Java, Scala, and Kotlin, but they are all executed in JVM (Java Virtual Machine).
Node.js Full-Stack Developers
Node developer skills:
- Frameworks suitable for Node.js: Express.js, Nest.js
- Web Sockets and REST API
Python Full-Stack Developers
Python – A universal programming language for everything, starting from educational tasks and up to working with neural networks.
Python developer skills:
- Python programming language
- Django/Flask framework
- REST API
- OS Linux and Nginx web server
- Cloud services
Java Full-Stack Developers
Java – It is one of the most popular and frequently used programming languages. It is functional on plenty of operational systems for various processors. Java components are easily accessible and there are no issues with ready solutions.
Java full stack developer skills:
- API Java EE specification
- Spring (Spring MVC, Spring Boot, Spring REST, Spring Web) Framework
- HTTP-server Apache
- Google Cloud and Azure Cloud services
- Servlets, JSP, and microservices
PHP Full-Stack Developers
PHP – It is a server scenario language created especially for web development. It is handy when creating templates, and themes and expanding standard HTML possibilities.
PHP developer skills:
- PHP language
- Framework Yii2/Symfony/Laravel
3. Basic Design Skills
Full-stack developers need fundamental design strategy skills to create attractive and user-friendly websites. Basic web design principles include UI/UX design and its prototypes.
4. Git and GitHub Experience
Git, a popular version control system, allows developers to handle every step of the software development process. Its bug fixing and tracking efficiency compare favorably to other control systems.
GitHub is a platform that allows full-stack web developers to work and manage many projects simultaneously. As the name implies, it creates a hub for communication and interaction with other developers. GitHub uses git features to provide an ideal platform for developers.
5. Databases and Web Storage
Almost all websites have a database in which all application data is stored. For example, if you have an e-commerce site, this will carry data about your products and users.
Part of the full-stack developer’s skill is the ability to write queries to call up the right data on the site when needed. Knowing the data structures is also useful here. This way, data is stored so that it can be queried in the most efficient way possible. Working with database functions such as storage, creation, control, processing, and deletion of data is an important part of the job.
The two main types of databases are SQL (relational) and NoSQL (non-relational). A popular NoSQL database service is MongoDB.
6. HTTP and REST
The Hypertext Transfer Protocol (HTTP) is the basis for data transfer on the Internet, such as loading webpages, streaming videos, and other forms of communication between web browsers and web servers. It’s the basis of most of our everyday interactions on the Internet. HTTP enables communication between web clients and web servers through requests and responses.
Representative State Transfer (REST) is an architectural standard. It makes it easy for computer systems to communicate with each other. RESTful systems use HTTP to collect data and perform various operations. REST provides communication between the front-end and back-end.
7. Soft Skills
If you hire a full stack developer, you should also understand whether they have the necessary personality characteristics to handle the job. For example, a talented full-stack developer should have the following soft skills:
