Let’s start from the most basic one and discuss everything you need to know about Full Stack developers.

What Is Full Stack Development?

The term ‘full stack’ represents the ability to work on both – front-end and back-end parts of the application. Full stack development refers to the development of cutting-edge, modern, end-to-end applications including frontend (client-side) and backend (server-side) development.

A full stack developer is a person who possesses skills to develop complete web apps including front-end and back-end parts. Full stack itself represents a ‘complete’ stack that includes everything you require to build modern-day applications.

A full stack developer must have proficiency in one or more frontend frameworks and one or more backend languages.

A Brief History Of Full Stack Developer: How Full Stack Term Came Into Existence?

The full stack term is not new.

Yes, it existed since the evolution of software development, especially web development. In the early 80s and 90s, many programmers single-handedly coded entire applications without requiring different skilled professionals, technologies, and programming languages. This was about the time when hardware and memory devices were limited and not so advanced.

With the introduction of client-server programming and the advent of innovative technologies in the 1990s-2000, software development started becoming more layered with the server part, database, presentation, and business logic.

The full stack term was coined after the 2000s(the exact year is not known) when web development required different expertise within layered structures of the development. In addition to this, different client-side and server-side frameworks entered the development market, requiring separate professionals to work on frontend and backend.

At present, full stack developers are dominating the web development market and enjoying top positions. Full stack development skills are one of the most demanded skills for the upcoming years.

What Is The Future Scope Of Full Stack Developer?

Becoming a full stack developer is almost like T-Shaped developers who not only possess deep knowledge of any particular area but also familiar with a broad range of generalized concepts. This will help them become all-rounders and difficult to replace. They are collaborative, knowledgeable, and focused, significantly contributing to building happier, productive teams.

The future of Full stack developers seems promising as they have knowledge of every layer of the development including presentation, business logic, and database layer. But, at the same time, this role demands staying updated with a range of technologies and frameworks and proficiency in more than one language/framework.

Why Full Stack Developers Are In Demand?

One of the key reasons why full stack developers are in demand is flexibility. Flexibility to work with a range of tools and frameworks for backend and frontend. This saves time and cost especially for startups and mid-sized businesses.

In the case of large and established organizations with thousands of users, experts, and specialists in one technology/tool are preferred over full stack developers. Although, many tech giants are hiring full stack developers due to their all-rounder and ‘jack of all trades’ approach. They are more valuable to any company that wants faster time-to-market and cost-efficient solutions.

This versatility is a unique characteristic of full stack developers which makes them valuable than others. Today’s development practice involves diverse tools and skills like database management, API development, coding in an integrated environment, and an agile approach to development. The increasing demand for full stack developers makes it one of the hottest professions among developers and students. Higher salaries, flexibility, future growth, and continuous learning are some of the perks that come with this job.

Full stack developers can develop applications single-handedly, reducing the number of different roles required to hire for development. This saves a lot of time and cost especially for startups and small-scale enterprises.

The salary of a full stack developer is generally based on experience and technical expertise. Full stack developers are more suitable for startups and SMEs where they can replace big teams and develop faster.

There are several myths related to full stack developers. Let’s discuss those in detail.

What Are The Myths Of A Full Stack Developer?
  • They Are Experts In Everything:

They are highly skilled in one or two areas but they are not experts in everything. They must have a working knowledge of one frontend and one backend language and basic knowledge of every component required to build modern applications. They are more like generalists rather than specialists. They have a general idea and understanding of all relevant technologies but they do not possess deep and in detail knowledge of each.

They lack in-depth skills and deep expertise in each component and that’s the reason companies need professionals who are experts in one language/framework/component.

  • They Can Be Substitute For Team Of Developers:

Up to some extent and especially for startups and small businesses, this is true. But this limits the options of choosing a tech stack. If you are planning to hire a single full stack developer, you need to depend on the skills of developers rather than choosing from a variety of tech stacks to meet the needs.

  • They Are One Man Army:

This is also true up to some extent. But when it comes to larger applications and the use of diverse technologies in production which is the case in today’s environment, a full stack developer will not be a suitable option. With full stack developers, your focus will be limited along with tech stack and that can become a concern for scalability.

  • Hiring Full Stack Developer Comes With Challenges:

If they leave your organization, you will have to face an urgent crisis to hire other professionals to meet the needs. Organizations that are relying on a single full stack developer are often limiting themselves to one person or a limited number of technologies.
