Ajax, or Asynchronous JavaScript and XML, is a powerful development technology used to create faster and more dynamic web applications. This means that an AJAX developer or engineer helps businesses create the most responsive web experiences for users. Through its interaction with the server, AJAX can improve the performance of web applications, aiding in loading time and overall responsiveness. With Ajax, web developers can create complex user interfaces from multiple data sources that use far fewer resources than traditional web-based applications. Ajax-enabled applications also tend to be more accessible, being compatible with a wide range of browser technologies such as HTML, CSS and JavaScript.

An AJAX Developer's expertise helps to build look attractive but simple user interfaces. They take complex application architectures and make them simpler for users by defining how to collect data from different sources and how to display it in a unified interface. They also make sure that their applications are device-independent and compatible with their intended devices.

Here’s some projects that our expert AJAX Developers made real:

  • Creating login pages quickly and securely
  • Building hotel websites with powerful API integrations
  • Designing efficient user interfaces to enable sorting of posts
  • Facilitating likert scale forms using modern frameworks
  • Developing single pages using databases, PHP, and libraries like Handsontable
  • Constructing efficient digital download scripts using core PHP
  • Expertly uniting CSS, Bootstrap, MySQL, AJAX, and JQuery
  • Crafting easy Shopify buttons for adding subscription products
