In app development, only professionals with versatile skills who always have higher demands are called full stack developers. Full stack developers are known for their versatile skills with front-end and back-end development. They are often regarded as the masters of multiple development skills who can build an app from start to finish.
Since they are high in demand, you need to know the critical skills to look for when you hire full stack developers for your app project. They are expected to have a strong command of all key languages and development frameworks widely used for both client-side and server-side development. Full stack developers are also experienced enough to give the app project the right direction regarding development and design decisions.
Throughout this blog post, we will explain the must-have skills of full stack developers. But before that let us spare a few words on defining the full stack developers and the leading full technology stacks.
Every app project has two main components: client-side or front-end and server-side or back-end. Apart from these two major parts, the app also should have a database. Now for all three components, there are different development technologies.
Leading back-end development languages include Java, PHP, Swift, .Net, Kotlin, C++, Ruby, Objective C, Python and leading back-end development frameworks include NodeJS, ExpressJS, Ruby on Rails, Laravel and a few others.
Leading database technologies used by most app projects include MySQL, MongoDB, PostgreSQL, NoSQL and several others.
Usually, a full stack developer is skilled with at least one front-end, one back-end, and one database technology to develop the app project's client-side and server-side. Companies often hire remote developers with full stack development skills to fulfill their server-side and client-side development needs. There are also full stack developers with expertise in multiple languages and frameworks for front-end, back-end and database.
Over the years, some technology stacks remained widely popular for their effective role in building apps. The leading full technology stacks include MEAN (MongoDB, ExpressJS, AngularJS and NodeJS), MERN (MongoDB, ExpressJS, ReactJS and NodeJS), LAMP (Linux, Apache, MySQL, PHP), MEVN (MongoDB, ExpressJS, VueJS and NodeJS) and a few others.
Now let us explain the key technical and soft skills you should look for when hiring full stack developers.
A full stack developer should be fully versed with the common and widely popular open-source repository where developers update all the code changes for their projects and track versions. The platform offers a rich reserve of coding examples and documents that developers often access.
A full stack developer should have a GitHub account with an excellent track record of contributions. It is expected that the developer is also versed with the SourceTree interface to handle code updates without getting distracted from the project.
HTML happens to be the basic or foundational coding language for the vast majority of web interfaces. For any web developer having a strong command of using HTML language to incorporate special features and to give a structure to the web page is important. The developers use HTML to create forms to connect the server with the client-side of a website.
CSS or Cascading Style Sheet accompanies HTML to determine how all the HTML coded elements are displayed on the web page. In that respect, it is the crucial language to determine the look and feel of a website. The CSS decides on colors, fonts, layouts to buttons, and all other visual elements in the web design. CSS also offers several abstract functions that can be used to follow common design practices instead of designing every element manually.
The following are some of the most sought-after back-end development skills that a full stack developer should have.
Apart from all these three technologies we mentioned above, a full stack developer can also be versed with leading back-end development languages such as Java, C++, Kotlin and others.
Web apps need integrated data storage to access later or contextually. This is why the web app project must have a robust database system. The full stack developers should be well-versed in how data storage can be optimized and relational database systems can be used to ensure faster data processing and strict data security.
An expert full stack developer not only has command over managing databases but is skilled enough to create and make use of different database queries. He should also be skilled enough with the practices to manage both relational and non-relational databases. The full stack developer should also be versed with the database formats or syntaxes such as XML and JSON.
A full stack developer handles the entire web app development project from development to deployment and he needs to ensure superior performance irrespective of conditions. This is why he is required to choose the right web architecture for the project as well.
He should be knowledgeable about the web app structure and the user interface to ensure lightning-fast loading time without compromising the content and features. The full stack developers should understand the structural attributes and UI elements such as DNS, cloud infrastructure, database servers, etc.
Since full stack developers need to establish smooth collaboration between the server-side and the client-side of an app, they often need to use web services to achieve desired results. Certain web services such as REST and SOAP have already been considered widely useful for state management and server communication. Developers should be well versed in using these two web services tools to facilitate faster and efficient data sharing and transfer between the server and the front-end.
An app project continues to go through several subsequent updates and each update brings coding changes, feature additions and UI/UX changes. There are version control files to register these changes and document them. This allows the developers to recall any changes and evaluate them.
These version control files are created by developers separately when they develop the app. These version control files allow other developers to collaborate on the same project.
You are wrong if you think a developer has nothing to do with the app design as he is entitled to look after only the app development. A full stack developer handling responsibility for the entire project needs to know the design practices and tools to decide on the design elements that work best for the app project. A comprehensive understanding of wireframing, mock-up design and dynamic prototyping will be crucial skills for a full stack developer along with other skills.
Lastly, a full stack developer should also have the right personality to work with the existing team and the project manager to bring the app project to its desired fruition. Some of the most sought-after soft skills and personality attributes for a full stack developer include superior written and verbal communication skills, time management, leadership attributes, ability to handle multiple tasks and responsibilities, creative brainstorming, etc.
