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

  • Developing single pages using databases, PHP, and libraries like Handsontable

    Our production platform is already live on CodeIgniter (MVC) with a Bootstrap front end, Ajax-heavy JavaScript, a MySQL/SQL back immediate need is to improve code maintenance so the application can scale cleanly while we continue to ship new functionality. What needs to happen: • Track down and resolve outstanding bugs that affect both the customer dashboard and admin area. • Build out several new features now on the roadmap, using the current CodeIgniter architecture but written cleanly enough to migrate later to Laravel or a Node.js micro-service. • Refactor brittle controllers, models, and SQL queries for faster response times and lower complexity.
