Web development covers the tasks involved in creating and managing web sites and applications, hosted on an intranet or the Internet. It involves the coding and programming that enables a site to function.
Unlike web design, which focuses on the appearance of a website, web development deals with the technical and functional aspects. This expertise encompasses a wide range of tasks: writing scripts on the client and server sides, managing databases and integrating elements supplied by designers or web copywriters.
A functional, optimised website is often the first interaction a company has with its customers. Web development meets this need. It enables the creation of customised online platforms: showcase sites, web applications or e-commerce shops.
Web development also makes it possible to improve the efficiency of internal processes through tailor-made intranets, collaborative applications and data management solutions. These tools facilitate communication, improve productivity and reduce costs.
Back-end development is the engine that runs the site in the background. It manages the site's databases, servers and security.
Using certain programming languages, developers design applications and systems capable of storing, managing and transmitting data between the server and the user interface.
Front-end development concerns everything that users see and interact with on a website. Developers translate the mock-ups designed by the designers into code (HTML, CSS and JavaScript).
They then optimise the site for different devices (responsive design), and ensure that it complies with good SEO practices.
