Full-Stack Developer: the profile as a professional

What is a Full-Stack Developer?

A Full-Stack programmer is a professional with various computer skills.

It is about a “hybrid profile” that can perform both in the Front-End and in the Back-End when developing web pages and applications: he understands their architecture and is capable of working with databases and servers, while optimizing the interface to ensure a good user experience.

His work includes:

Software design, development and optimization.
Clean code writing for Front-End and Back-End.
Design of user interactions.
Localization of specific problems in the interface.
Creation of servers and databases.
Software compatibility with other platforms.
Responsive application design.
I work with designers to create new features.
Development of APIs and RESTful services.
Maintenance of security and scalability in the development of the project.

Th multi-skill nature of this profile allows this type of programmers to have notions related to the development of: databases, networks, hosting, servers, APIs, HTML, JavaScript, Angular JS, Bootstrap, Java, C++ or Python, although not all Full-Stack Developers dominate all of these languages at the same time.

What they do have in common is control over Front-End and Back-End technologies.

And this is its main advantage: while the Front-End developer works on the part of web development that is visible to users and the Back-End developer works on the data access layer of the software, device or application, the Full-Stack Developer does both. He is dedicated to the web development of the interfaces and additional tasks of the Front End Developer, but still performing the tasks of a Back End Developer.

Basically it’s like having the best of both profiles in a single professional.

Knowledge and skills of a Full-Stack developer

Although the functions of a Full-Stack programmer depend on the structure and needs of each company, they dominate programming languages, frameworks and technologies.

Front End Technology

You must have knowledge of HTML5, CSS3, JavaScript, and libraries like jQuery, LESS, Angular, and ReactJS.

Development languages

You must know at least one development language such as Java, Python, or Ruby. They are programming languages that every kind of fullstack web developer or fullstack app developer has to know.

Database and cache

MySQL, MongoDB, Oracle or SQL Server are the main databases with which a Full-Stack programmer will work on a daily basis. You should also be familiar with caching mechanisms such as Varnish, Memcached, or Redis.

Design

It is recommended to have design knowledge, both prototyping and UI/UX.

Servers

Linux training is recommended for better server administration.

Version Control System (VCS)

Having knowledge of Git helps Full-Stack Developers to understand and get the latest code, update parts or make changes to it.

Other knowledge and skills

In addition to the above one, it is recommended that this type of professional know HTTP and REST protocols, APIs and business logic.

Finally, he must combine this knowledge with soft skills such as:

Leadership
Fluid communication
Interpretation and orientation of results
Teamwork
Global thinking
Organization
Creativity

Examples of technologies and frameworks used in Full-Stack development

Differences between programming language, library and framework

These three concepts, although related, should not be confused.

Programming language

Programming language is a tool to develop software or programs for computers.

It is made up of a series of symbols and syntax and semantic rules that define the main structure and give meaning to its elements and expressions.

Some programming languages are PHP, Java, C++ or Python.

Library

A library is a code snippet used to solve a problem or functionality by a software.

Libraries can be homemade (those developed by a programmer) or external (they are created by experts and are used in a general way).

Some examples of the latter are Jquery, React, and the Dojo Toolkit.

Frameworks

It is a template for developing software that facilitates programming and task automation.

Frameworks prevent redundant code and errors, and make programming safer and easier to maintain.

There are different types of frameworks (for web applications, AJAX technology, multimedia, content management, etc.), among which Vue.js or Angular JS stand out.

The main difference between frameworks and libraries is that while the former provide you with a global framework to build applications, the latter solve specific problems.

Examples of Full-Stack developers you can hire

A Full-Stack developer is defined as “all-round” because of his or her ability to intervene, both in the visible side for the user, and in the computational logic that regulates the proper functioning of a website or an application.

Hence he plays a cross role in many technological projects.

The are many specialists within the fullstack development:

Full-Stack React Developers

React is an open source JavaScript library that is very useful for creating attractive interfaces. Its use brings advantages in terms of speed, reusability, performance and flexibility. In fact, debugging code with React is easy: a react fullstack developer can design a simpler view and let React update and render components based on data changes.

Angular Full-Stack Developers

Angular is a platform for building web applications for mobile and desktop devices. This framework is recommended for the development of modern Front-End applications, of medium or high complexity, robust, scalable and optimized. This is why Angular FullStack developers are in high demand.

Full-Stack JavaScript Developers

JavaScript is used in 90% of websites and mobile apps for scripting. This programming language is perfect for creating interactive sites with features that enhance the user experience. In addition, it is the only language that allows Full-Stack to work in any type of programming.

Full-Stack Node.js Developers

Node.js is an open source, event-driven, cross-platform runtime system. It allows you to run JavaScript code and create back-end applications on the server side. Node.js developers have a command of JavaScript and Node.js technology, and a hands-on control of the most popular frameworks.

Full-Stack .NET Developers

This type of programmers design, adapt and develop personalised applications according to specific needs and objectives. They can implement software and provide support and maintenance, while automating processes or testing applications and programs. The Full-Stack .NET developer must have knowledge of HTML, CSS, and JavaScript.
