Is Full-Stack Developer A Vaccine For Startups?

There's a wise old saying: "Working with a full stack developer can lead to better technology solutions." And in recent years, this saying has proven to be true for many startups.

In the last few years, we have heard a lot about full-stack developers.

We know that a full-stack developer is a person who has complete knowledge of the different layers involved in application development. Whether you are dealing with the front or back end or working in the business layer, they take care of everything with ease.

But did you wonder why a full-stack developer is so important for a startup? 

This blog will answer all such queries. So let's get started.

The Demand for Full-Stack Developers

As per a development report published recently, it was seen that there had been a 206% increase in demand for full-stack developers from 2018 to 2020. This is because more companies seek multifaceted skills. 


Full-stack developers or a full-stack development company are able to take care of all the development needs of your project. So whether it's front-end or back-end development or enterprise layer development, they are competent to work on everything. You can always hire full-stack developers for your business needs.

What can a Full-Stack Developer Do?

In terms of software development, there are front-end developers and back-end developers. Front-end developers create the interface, while backend developers design the software. 

A full-stack developer can do everything. They take care of application design, server-side scripting, client-side coding, coding, administration, database creation, and any other project development needs.

The following are the responsibilities of a full stack developer that you hire:

  • Manage web development

  • Code applications and programs

  • Solve problems

  • Coordinate with other team members and developers

  • Think about testing techniques for web applications

In short, a full-stack developer has a strong understanding of the technologies that determine how a website looks, functions, and functions. The said developer must have a working knowledge of HTML, JavaScript, CSS, PHP, Angular, Ruby, MySQL, Node, MongoDB, Apache, etc. The knowledge to work with animations and design will add a bonus point to a candidate's portfolio.

Over time, the skills required for full-stack development have expanded and evolved. Long ago, the LAMP stack included Linux, Apache, MySQL, and PHP. It is more than MEAN and beyond today. 

Currently, a typical mean stack development service provides developers who can perform front-end development using JavaScript, HTML, CSS, and other JS frameworks; for the backend, they use Express and Node, and for databases, they follow MySQL and MongoDB.

Top Reasons to Hire Full-Stack Developers

  • Effective troubleshooting

When hiring a full-stack developer, companies are always looking for candidates who are capable of solving a problem. Full-stack developers are competent to handle all aspects of the project. They prove to be a practical solution for startups that are not willing to spend more money on many developers.

  • Wide range of technology skills

The main reason companies choose full-stack developers for their projects is their potential rather than their knowledge. Over time, companies teach them the skills they want them to have. In this way, in a few years, they learn different technological skills as the company expands.

  • Executive and management skills

Companies like to have people with business experience on board. A full-stack developer has the knowledge and expertise to work on the front-end, backend, and media architecture layers. This means that they are capable of performing better than an individual front-end or backend developer.

  • Economic

As full-stack developers can develop all aspects of a project, it is not necessary to form a team of experts. They will easily handle the project without help from anyone. This will save the right amount of money for the recruiting team.

  • Faster development process

Full-stack developers know different technologies, tools, and techniques. This means that when they take the project, they will be able to complete it faster. They will spend less time discussing and collaborating with the team on the project.

Benefits of Full-Stack Developers for Startups and Small Businesses

  • Established developers

Full-stack developers have enough experience to create outstanding features for the final product, which will be able to excite the market. They have the ability to build a complete product from scratch. If you want to gain some benefits from your product, you will have to collaborate with these experts. Remember that not all developers are capable of handling the project from a 360-degree perspective.

  • Versatility

A full-stack developer is able to work equally well on the front-end and the backend of a website or application. Front-end developers write code using JavaScript, HTML, and CSS, which are able to control the appearance of the solution and how it interacts with the browser and users. Backend developers write code that connects the website or application with other content management systems. A full-stack developer is capable of handling both tasks. They are focused on meeting customer expectations and finding solutions on their own.

 

  • Vast experience

Full-stack developers take on different web projects. This has helped them gain in-depth knowledge of various technologies and the experience to find quick solutions in web and application development. Such understanding and knowledge improve the performance of the project and its reception in the market.

  • The largest photograph

The main advantage of choosing a full-stack developer for your project is that they will come up with the complete structure of the project and offer their valuable input to the project as needed. Their services go beyond project development to maintain and optimize existing solutions.

  • Upgrades

Web design plays a crucial role in whether most people love or reject a website. Full-stack developers will make sure that the website is pretty user-friendly. They keep up with trends and technological innovations. To make sure their clients get the best interactive and responsive website, the developers implement intelligent features in their projects.

  • Troubleshooting issues

Full-stack developers have complete knowledge and experience of the different stages and aspects of website development. They are skilled enough to identify problems that may arise during the development of the project. They will propose long-term solutions to ensure that the website or application works optimally based on their findings.

  • All-inclusive

In addition to leading your web project and enabling enhancements to it, full-stack developers move to the level of representing your product to stakeholders or your company at conferences. They can move quickly from one operation to another with ease, streamlining the development process.

  • Economic

If you are on a tight budget but want to create a fantastic website, then you should consider hiring full developers for the job. You can even think about having a remote full-stack developer for the project. As such, a developer is capable of handling all aspects of project development; you won't have to hire different people for the job. This will save you a lot of money.

  • Delivery time

It will be easy for developers to share responsibilities among the team and coordinate with each other for better project progress. This will result in faster delivery of the project.

  • Project ownership

When you hire full-stack developers for your project, you can be sure that they will take care of everything. Such a developer will be able to develop MVP from start to finish. If you hire a full-stack developer in the middle of the project, even then, you'll find a way to join the flow seamlessly. Such a developer will work towards quality control of the design project.

 

 

Summing Up

So these were the advantages of hiring a full-stack developer. I hope you have noted the changes that a full-stack developer can bring to the table and in your company. However, working with a full-stack developer is the best way to work with a top full-stack development company in India.
