What skills to mobilize for developing a Web Application?

Skills to Mobilize for Developing a Web Application”

An web application is a software accessible via a web browser, without the need for installation on a local device. Unlike applications that you install directly on your computer or smartphone, a web application functions like a website: you use your browser to access the application, and each action you take is processed by a remote server that sends you the results, all happening almost instantly.

Platforms like Google Docs, Trello, Canvas, or online CRMs are concrete examples of web applications. Web applications offer unprecedented flexibility and accessibility, allowing users to access their data and features from any internet-connected device.

However, designing and developing an effective and performant web application is no small feat. Each component, whether it’s the user interface, business logic, or security, requires specific expertise. Therefore, mobilizing the right tech profiles is imperative. Making a mistake in choosing the right skills can lead to undesirable consequences, ranging from a poor user experience to critical bugs or security vulnerabilities. In this context, understanding the necessary skills and profiles for developing a web application is essential to ensure its success and longevity.

The Pillars for Setting Up a Web Application

In the vast world of web application development, some skills are fundamental. These skills form the foundation on which every successful application is built. Whether it’s visual design, user interaction, or internal mechanics, each element plays a crucial role. Let’s delve into these essential skills that make the difference between a simple web page and a functional web application.

First and foremost is the design of interfaces and user experience, which is paramount. This is where UX/UI Design comes into play. An application can be technically perfect, but if it’s not intuitive or pleasant to use, it may not achieve the desired success. UX (User Experience) designers focus on how the application works, ensuring it’s logical, smooth, and meets user needs. Meanwhile, UI (User Interface) designers refine the appearance: colors, typography, spacing, ensuring that the application is not only beautiful but also functional.

Once the designers have created mockups or a prototype, it’s time to develop the application. When you navigate a web application, everything you see and interact with directly is the result of Front-end development. This includes layout, design, animations, and interactivity. Key skills here include mastery of languages like HTML (for page structure), CSS (for style and formatting), and JavaScript (for interactivity). Additionally, knowledge of popular frameworks like React, Angular, or Vue.js may be essential for developing more complex and interactive applications.

However, if the Front-end is what you see, Back-end development is the engine in the background. It deals with business logic, data storage, security, and performance. Back-end developers work with languages like Node.js, Python, Ruby, or Java and manage databases like SQL or MongoDB. They ensure that when you submit a form or take an action on a web application, the data is processed, stored, and sent correctly.

In summary, UX/UI design, Front-end development, and Back-end development are the three fundamental pillars of a successful web application. These areas embody the major skill requirements for producing an application that is user-centered, aesthetically pleasing, and functionally robust. Ignoring any of these pillars compromises the quality and effectiveness of the application. Thus, if your company is considering internally developing a web application, it’s imperative to mobilize and value skills related to these essential domains.

Additional Skills to Mobilize for Application Development

Other skills, while not central, play a crucial role in producing, securing, and optimizing the application. It’s important to note that the list below is not exhaustive and can evolve depending on the nature and complexity of the application to be developed. However, among the areas of concern, the following points can be mentioned:

  1. Project Management: Rigorous project management is essential for any web application project. This involves planning, resource allocation, progress tracking, and smooth communication to ensure coordination among teams. Methodologies like Scrum or Agile can be employed to ensure on-time delivery and adherence to specifications.
  2. Cloud Infrastructure: Setting up a network infrastructure is necessary for developing your application. Today, the cloud has become an indispensable solution. Managing a cloud infrastructure requires a deep understanding of cloud computing services such as AWS, Google Cloud, or Azure. This includes configuration, deployment, scalability, and cost management. Sometimes, in the case of hybrid infrastructures, the ability to integrate cloud resources with on-premises infrastructures is also essential.
  3. Security: Nowadays, cyberattacks are common. Security cannot be overlooked. This includes protecting user data, preventing attacks, and establishing protocols to respond to incidents.
  4. Testing and Maintenance: Before going into production, it’s essential to ensure that the application works as intended. This requires, among other things, unit testing, integration testing, and user acceptance testing to ensure that each feature meets requirements.

If the fundamental pillars of a web application define its basic structure and operation, complementary skills refine, secure, and optimize that foundation. They ensure that the application, whether simple or complex, not only meets user needs but also market and technological requirements. Taking the example of a banking application, expertise goes beyond design or development. Business understanding is crucial, for example, to develop credit simulation algorithms that take into account interest rates, loan durations, and risk profiles. Similarly, seamless integration with other systems, such as payment platforms or
