    I have all the visual pieces ready— decompiled table layouts, colourful card sets, buttons, and pop-ups taken from the reference app “Rummy R13.” What I do not have is the core game itself. I need you to turn those assets into a fully-playable, multiplayer 13-Card Standard Indian Rummy experience built with HTML, vanilla JavaScript on the front end, and Node.js + on the back end.

    Hi, I’d love to help you transform your Shopify fashion store into a modern, fast, and conversion-focused shopping experience. My approach would include: Reviewing your existing Shopify theme and identifying performance issues. Optimizing Liquid, CSS, and JavaScript for faster loading. Refreshing the storefront design while maintaining your brand identity. Improving collection pages, product pages, navigation, and mobile responsiveness.

    I’m building and iterating on a suite of web applications and want every line of code to move fast without sacrificing quality. You’ll jump straight into a modern stack where Python handles the heavy lifting on the back end and JavaScript drives interactive front-end experiences. Day to day you’ll design new features, refactor legacy pieces, write and debug code, and resolve production issues as they surface. The twist—and where you’ll really shine—is how comfortably you weave AI into that workflow. I already rely on GitHub Copilot for rapid scaffolding and on OpenAI GPT-3 for tasks such as test generation, documentation drafts, and quick proof-of-concept scripts. You should be just as fluent, knowing when these tools speed things up and when t...

I do not have the original source files, so you will have to re-create the HTML, CSS, JavaScript, images, fonts—everything visible on the front end—and make sure the finished page behaves exactly like the current one. No design or content tweaks are wanted; the copy, colours, layout, animations and any form or click-to-call behaviour must match the original.

    My content-management web application was running smoothly until the original developer, unhappy about a payment dispute, deliberately disabled it. The stack is a mix of JavaScript on the front end, Python services, and a PHP admin layer. I still have full server and repository access, so the code is intact – it just no longer serves pages or lets me log in. What I need now is a calm, skilled developer who can quickly trace how the site was taken offline, roll back (or rewrite) whatever kill-switch was planted, and get the whole CMS live again. Along the way I want the codebase reviewed for any other hidden “time bombs” so I’m not left vulnerable in the future.
