The role of an application software developer in this tech-appropriate age is critically BIG. The same is the responsibility bestowed on software application developers on app development projects. An efficient developer can turn an idea into an amazingly simplified app that can change the way the world works.

Let’s check the essential roles, responsibilities, and adequate skill demands of application developers

What is an application developer?

 A professional application developer is an impeccable source code creator of the software. Based on the specialized field, application developers involves in the end to end software development life cycle. They create, test, deploy, and help to upgrade software as per the requirement of clients. Also, developers work coherently with designers, analysts, and computer engineers to bring out the proposed quality of software applications. 

The roles and responsibilities are;

  • Analyze the ideas, business models, and user requirements to formulate a design strategy to carry out.
  • Act as a tenant to draw out a workable application design and coding parameters with the essential functionalities
  • Breakdown the process into multiple packets to distribute to other relevant technology project teams
  • Develop various process flow diagrams and working models to streamline the process
  • Co-ordinate the development cycle and attest the compatibility of different modules
  • Supervise and conduct the performance test and trials to ensure a hassle-free user experience
  • Records and document each phase of application development for further reference and maintenance operation
  • Deploy and install the applications to demonstrate the successful performance of software as per the client expectation
  • Fix the problems arising across the test cycles and continuously improves the quality of deliverables
  • Communicate with other application development partners and technology arbiters to deliver excellent output

What are the skills required to be an application developer?

To perform the roles of an application developer, a set of general and specialized skillset is essential. Apart from robust technical and analytical knowledge, an application developer could solve any software design conditions

Plus, a programmer should be an innovative ideator and a creative person. The ability to communicate eloquently and patience to listen to the user recurrently adds value to the professional quality of app developers. In short, professional application developers should possess all the skills required to carry out -Planning-Estimation-Design-Development-Testing-Support and Maintenance in a project cycle.

Key Skillsets

Software Development Life Cycle(SDCL): Skilled application developers thoroughly break down the development process such as analysis, study, design, coding, testing, launching, and support. Understanding the SDCL process helps developers to handle the entire development cycle and coordinate the necessary services at the right moment. 

UX/UI Expertise: As the wining-quotient of building an application is its receptiveness among customers. User Interface and User Experience are the key factors that determine the success rate of any consumer application software. Hence, possessing creative application modeling skills and user interface coding techniques helps developers to stand a chance. 

Algorithm and Data Structure: This is the essential counterpart in programming. Without consuming too much time and data, getting skilled in data structuring and optimized algorithm building ultimately helps application developers to meet and surprise users. 

Programming Language: A comprehensive knowledge of fundamental, as well as high-level programming languages such as PHP, Java, JavaScript, HTML5, C ++, Xcode, SQL, Objective-C, Swift, RUST, GO, KOTLIN, is a recommended skillset. However, developers can specialize in any of them based on their field of interest. Yet, having a decent command of a couple of these languages could gain professional advantage.

Networking and Testing: Acquiring necessary networking skills is imperative to an application software developer. It helps to picture out the network architecture of client-server and design the essential infrastructure protocols and gateways while framing the development process.

Cross-platform Software: Versatility is an appreciated attribute in the application development market. If programmers can offer cross-platform skills, it can stand them out from the crowd. The skill to weave codes on cross-platforms such as Codename, PhoneGap, Appcelerator, NativeScript, etc., enables a developer to satisfy the consumer-based software clients. 

What are the Different Types of Application Developers?

To find solutions over the rising need for diversified application development requirements on various platforms and methodologies, companies are in search of different types of application developers. 

  • Front-end Developer: Designing the application user interface, user experience, and anything that can enhance the aesthetics of application software is performed by front-end developers. They would be adept in languages such as Javascript, CSS, HTML, UI frameworks, etc. Plus, they are experts on the app development frameworks as if Foundation, Bootstrap, AngularJS, jQuery, Ajax, etc.
  • Backend Developer: Backend developers decide the scalability of applications. They work at the backend to integrate appropriate functionalities, databases, logging, and email systems. Those kinds of developers have a good command over languages like Python, Ruby, Scala, C++. Go etc.
  • Full-stack Developer: Full-stack developers have decent expertise over Front-end and Back-end development. Therefore, they require a complete understanding across server-side, and user side works. 
  • Mobile Application Developer: Native and Hybrid application developers would be there in this group. They are very familiar with different Application Programming Interfaces (API) such as Android, iOS, Windows, etc. Also, they have exceptional knowledge in mobile app development tools and languages such as Java, Objective-C, C++,  
  • Game Developer: Game developers possess excellent creativity and designing skills. They are required to accustom to several development tools and mobile app development methodologies. An adept game developer would have a firm grasp on multiple frameworks such as OpenGL, WebGL, Unity 3D, DirectX, etc. 
  • Data Scientist: Algorithm for machine learning, predictive modeling, data visualization, and data analysis are writing by this sort of developer. They are exclusively proficient in database language, programming languages, machine learning models.  They demonstrate high-level programming expertise and multi-dimensional problem-solving capabilities.
  • DevOps Developer: DevOps professionals deal with system-level backed software development. They take care of deployment, management, and monitoring of applications. The primary tools they use are Kubernetes, Docker, Apache Mesos, Jenkins, HashiCorp Stack, etc.
  • Embedded Developer: Embedded developers write codes for system hardware such as microcontrollers, IoT devices, electronic devices, etc. These types of developers use C++, Jave, and related frameworks to perform the task.   
  • Test Engineer: This group of developers writes programs to test the diversified features and performance of applications. Test engineers are responsible for assessing the quality of the software application
  • Security Developer: Security developers consistently work on developing security scanning tools for software applications.  They discover the hidden vulnerabilities across the systems and networks. Security developers use scripting languages, i.e., Python, Ruby, and they would be familiar enough to understand C++ source codes. 


In short, the roles and responsibilities of application developers are not confined to specific operations. It requires an assortment of technical and analytical abilities. Likewise, the skills they need to possess are as diverse as their ever-growing dimensions. As technology grows to new complex heights, software developers have to acquire additional skillsets to climb it.
