JQuery / Prototype Jobs

jQuery / Prototype is an open source, Javascript library that is designed to help simplify the process of writing and managing code.

  • Automate processes with AJAX calls, allowing the user to refresh certain portions of their web page without having to navigate back or forward in the browser
  • Implement animation effects and effects flow while user is interacting with the application
  • Develop applications that work responsively across various devices, ensuring that your projects look as good on mobile devices as they do on desktop computers
  • Create complex forms with multiple plugin integrations, offering users a seamless experience when filling out those forms.

Our expert jQuery Developers have been able to make all sorts of projects come alive in our clients’ websites. Whether it's customization of components like sliders or creating complex web applications with tailored AJAX requests - a good jQuery Developer can help make your website come to life. If you've got a project for us to tackle, we'd love to hear it. Post your project on Freelancer.com today and hire a dedicated and talented jQuery Developer from our community.
