What is Web Development and what are its benefits for your projects?
Web development is about creating, building, and maintaining websites or web applications using programming languages and web development frameworks. The main reason why web development services are popular is the need for businesses to establish their presence on the web.
Building a website or a web application involves creating the user interface (UI) and user experience (UX), including the layout, colors, fonts, and images. It also consists in optimizing these elements for mobile and desktop, making the interface accessible to users, and facilitate the interaction between the user and the application. On the back-end, it involves scripting, server configuration, and database management. At the same time, it includes testing, maintenance, and ensuring overall functionality.
According to recent studies, over 4.7 billion people worldwide have access to the Internet. So, it’s obvious that having a well-designed and developed website is essential for any business that wants to succeed online.
On top of that, the number of mobile internet users is constantly growing, with approximately 92% of internet users accessing the web through their smartphones which proves the importance of responsive and optimized websites on mobile devices.
In a nutshell, a web developer, which is providing development services is responsible for:
- Establish a company's online presence via a web application
- Improve and optimize the performance of the website or web app
- Update and maintain the well-functioning of the website or web apps
In addition, depending on the terms of a contract between a company and a web developer, the second can assist with:
- Backup the data of the website
- Operate changes to the UI
- Migrate the website to another domain or platform
Usually, a web developer should have both soft and hard skills. The soft skills are related to communication and reporting, while the hard skills help in the development process.
If you choose to work with a web development company, make sure to keep in mind the following criteria in the selection process:
- The company should have experience in developing websites or web applications that are similar to yours.
- A solid portfolio that proves examples of their work.
- Communication abilities enough to pass through cultural, linguistic, and time-zone barriers.
- Transparency and proven track record
