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.

What I now need is custom code that turns the layout into a smooth, sales-ready experience. Here is exactly what I am after: • Gallery enhancement Gallery setup and display to be enhanced. • Gallery search Each gallery should expose a search bar fixed at the top. A visitor types any term that exists in the images’ IPTC tags and the relevant thumbnails filter instantly without a page reload. • Multi-image selection Every thumbnail shows a small checkbox underneath it. Visitors tick as many boxes as they like, then hit a single “Add selected to cart” button—no need to open each file. • Automated tiered pricing Before the...

I’m running the Prestige theme on Shopify and the cart has started misbehaving on mobile—both iOS and Android. Whenever a shopper adds a product, the cart grabs the previous item instead, so the cart is always one step behind. Swiping through product images or switching variations triggers a “SyntaxError: The string did not match the expected pattern,” blocking the add-to-cart action entirely. Removing items or updating quantities fails as well. Key pain points you’ll tackle: • Adding products, removing items, and changing variations must work reliably on mobile. • The cart should display the correct, current product every time. • No more SyntaxError on variant change. I haven’t modified the theme or added new apps recently, so the...
I am currently using Geo my WP, but I want to switch to WP Go Maps with the Pro Add on, and I’d like to configure the map with the following behavior: My website introduces many attractions around the world. For example, let’s say I currently have four attractions posted: Attraction A, B, C, and D, and they are all located close to one another. • When I’m viewing the page for Attraction A, the map should display: o Attraction A using Icon 1 o The other three attractions (B, C, and D) using Icon 2 • When I’m viewing the page for Attraction B, the map should display: o Attraction B using Icon 1 o A, C, and D using Icon 2 This is similar to what TripAdvisor does — for example: The main attraction shows with a unique icon, while nearby attractions appea...
I want to build a demo trading mobile app similar to Groww UI, but only for simulation trading (not real stock market integration). Features required: User registration (mobile, Gmail, password) Login system Dashboard with NIFTY50, BANKNIFTY etc. Demo buy/sell trading Deposit and withdrawal request system Admin panel: User management Deposit & withdrawal approval Add bank account / UPI Manual control of trade results (demo simulation)
Our PHP-based admin panel has suddenly become unreliable inside the User Management area. I can no longer add, edit, or delete users, role and permission assignments fail to save, and the user lists sometimes come up blank. I haven’t caught any clear error messages yet, so you’ll need to trace the problem directly in the code or logs. What I need from you is a quick, surgical repair: locate the root cause, patch the broken functions, and confirm that all three actions—create/update/delete users, assign roles correctly, and display user data—work again without introducing new issues elsewhere. You will have SSH/FTP access to the server, the Git repo, and a staging database to test against. Once everything is stable on staging, I’ll roll it to production. Ple...
