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 are involved 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
  • Coordinate 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 general and specialized skill set 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 Skill Sets

  • 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 winning 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 skill set. 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 a 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 the 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 to 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. Typically the code of a front-end developer is run on a web browser. 
    • Skills Required: 
    • More than the knowledge of computer science theory, a front-end developer must understand design principles and human machines.
    • They should be adept in languages such as Javascript, CSS, HTML, UI frameworks, etc. Plus, they are experts on the app development frameworks such as Foundation, Bootstrap, AngularJS, ReactJS, Vue.js, jQuery, Ajax, etc.
  • Backend Developer: Backend developers or also known as Server-Side Developers decide the scalability of applications. They work at the backend to integrate appropriate functionalities, databases, logging, and email systems. Backend systems can become extremely complex at times and added to this most of the time these complexities are not visible to the user itself. Google Search Engine is a good example of how complex the backend of the systems can get when compared to the front-end part which is simply just the UI. 
    • Skills Required:
    • These kinds of developers have a good command over languages like Python, Ruby, Node.js,  Scala, C++. Go etc. 
  • Full-stack Developer: Full-stack developers have decent expertise over Front-end and Back-end development and hence they could best be represented by the term “versatile”. Therefore, they require a complete understanding across server-side, and user side works. 
    • Skills Required: 
    • Backend languages- for example, Java, Ruby, etc
    • Soft skills- like good time management skills, patience, curiosity for learning, creative vision
    • Attention to detail
    • HTML/CSS
    • JavaScript
    • Git and GitHub 
    • HTTP and REST
    • Web architecture
    • Basic design skills
    • Database storage
    • NPM
  • Mobile Application Developer: these developers are required to have a good understanding of design and programming.  Native and Hybrid application developers would be there in this group.
    •  Skills Required: 
    • They are very familiar with different Application Programming Interfaces (API) such as Android, iOS, Windows, etc. 
    • They have exceptional knowledge in mobile app development tools and languages such as Java, Objective-C, C++
