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

    Urgent LearnPress Auto-Refresh Fix
    6 วัน left
    ยืนยันแล้ว

    I run a WordPress site that sells video courses through LearnPress and WooCommerce. 
Checkout is coupon-only—no payment gateway involved. The problem: • Once a student “buys” a course, it never appears under “My Courses” until the page is hard-refreshed. • Inside the course page the button still reads “Add to cart” instead of “Continue,” again until a hard refresh is forced. Both issues make users think their purchase failed. Key facts – Core plugins: WordPress, LearnPress, WooCommerce (no custom edits). – I did update a few plugins/themes recently, so the bug may be cache, Ajax or session-related. – The site must keep its current coupon-based flow; no payment gateway will be added. What I nee...

    Trophy icon Shopify Revamp With Live Customizer
    6 วัน left

    My Shopify store needs a focused upgrade on three fronts: the overall look and feel, the clarity and appeal of each product listing, and a faster, friction-free checkout. While polishing those basics, I also want to introduce an interactive customizer that lets shoppers tweak products in real time, watch a live order preview update instantly, and switch between color or size variations without page reloads. The new module should be fully embedded in the storefront, built with Liquid, JavaScript and AJAX so it feels native, loads quickly and works on every screen size. Please keep the code theme-update friendly and well-commented so future edits are simple. SEO and page-speed metrics must not take a hit after launch. Deliverables • Refreshed theme/layout applied across all pages ...

    I need help debugging a custom WordPress shortcode that integrates with the ProKerala Astrology API. The shortcode [svgnan_kundali] displays a form correctly on the page. However, when the user submits the form it redirects to /kundali-result/ which results in a 404 error. Expected behavior: The form should call the ProKerala API and display the Kundali chart on the same page below the form without redirecting. Website environment: WordPress Astra Theme Elementor WPCode plugin ProKerala Astrology API Hostinger hosting Task: Debug the shortcode or AJAX logic and fix the redirect issue so the API response renders correctly on the same page. Estimated time: 30–60 minutes debugging. Budget: ₹1000 – ₹1200 fixed price This is a small debugging task. Please apply only if you hav...

    Connect Form to Email & Sheets
    3 วัน left
    ยืนยันแล้ว

    The website is already live; the only task left is wiring the contact form so every submission: • lands in my inbox immediately, and • is appended as a new row in the Google Sheet I have waiting. The form is finished and visible on the site. It captures four fields—name, email, phone number, and message—and shows a thank-you message after sending. All styling, layout, and hosting are done, so the scope is purely the backend / integration logic. You are free to use PHP, JavaScript fetch/AJAX, Google Apps Script, the Sheets API, Zapier, or another lightweight approach—whatever delivers reliable email delivery (via SMTP or an API like SendGrid/Mailgun) and an instant Sheet update. The finished code should be: • Fully commented so I can adjust addresses o...
