    My Google Ads enhanced-conversion tags fire, but the conversions never process because the user-provided data isn’t being sent. Email addresses are captured only at the point of sale, yet no CSS selector or JavaScript variable was defined during the original setup to pass that data to Google. Here’s exactly what I need: • Add the correct selector or data-layer variable to capture the customer’s email (and any other available identifiers) at checkout. • Update the existing gtag/Google Tag Manager implementation so the hashed data reaches Google Ads in the required format. • Verify the tag in real time with Tag Assistant and confirm that enhanced conversions appear in the Google Ads diagnostics after 24–48 hours. Acceptance will be based on...

    I’m ready to launch a clean, fast personal blog and need a developer who can take it from blank repo to live site. The stack can stay lightweight—HTML5, CSS3, and vanilla JavaScript on the front end, with PHP (or Java if you prefer) handling any server-side logic. We’ll work in VS Code so everything stays transparent and easy to review. Core requirement: a working comment section that lets readers leave, edit, and delete their own thoughts while protecting the site from spam. I’m open to adding extras such as social media hooks or a search bar later, but for this first milestone the focus is the blog itself and the comment workflow.

    Our cloud-based accounting platform is built entirely with a JavaScript/Node.js back-end on top of MongoDB. During closed beta everything behaved, but the moment we opened the doors to a larger audience the application locks up under load—no gradual slowdown, just a complete system freeze that forces a hard restart. I need a seasoned engineer who can dedicate roughly 5–6 hours every day for at least the next three months to hunt down the root causes and redesign the platform so it scales smoothly. You’ll collaborate directly with me and two in-house developers; we work on GitHub, communicate over Slack, and deploy through a basic CI pipeline that will probably need tightening as part of this project.

    ...it, and be sure the video streams smoothly on all modern desktop and mobile browsers once you are done. While you are inside the codebase, the “Forgot Password” routine also needs attention. At the moment the form submits but the reset e-mail never arrives, so users get stuck. A reliable token-based reset flow, with clear success / failure feedback, is the goal. You will likely be touching JavaScript, the wrapper, a small slice of PHP back-end logic, and the SMTP configuration. Feel free to swap in another lightweight player if that proves faster than repairing the current setup, as long as MP4 support remains solid. Deliverables • Video player loads and plays MP4 files without manual refresh or extra clicks • Forgot Password feature sends working re...

    I need a senior-level full-stack developer who can dive straight into my existing WordPress theme, decode its current template files, and build three focused enhancements: • Add-to-Cart Menu ...theme’s PHP/JS stack. • Sales Price Indicator – inject a clear, branded visual cue next to discounted items. It should pull the “regular” and “sale” values already stored in WooCommerce and display a badge or percentage marker without slowing the product loop. I’m only after these modules and sections, not a full platform rebuild. You should be comfortable editing obfuscated or minified PHP, JavaScript, and SCSS, respecting child-theme best practices, and committing updates via Git so I can track changes. Let me know an estimated turnarou...

    My existing Quotex trading bot is written in Python and opens a WebSocket connection with the websockets library. It used to run flawlessly, but a recent Cloudflare JavaScript challenge now stops the handshake before it even upgrades to WebSocket. I need a clean patch that lets the script authenticate, obtain any required Cloudflare tokens or cookies, and then continue with the normal WebSocket flow. Whether you solve this by emulating a modern browser fingerprint, completing the challenge once and re-using the cf_clearance cookie, or by injecting the right headers in the initial HTTP upgrade request is up to you—as long as the result is reliable and headless. What you will hand over • Updated Python code (or a lightweight helper module) that completes the Cloudflar...

    My existing site is pure custom HTML, CSS, and vanilla JavaScript. I now need an add-on, self-contained contest area that will run every four months and then reset itself for the next round. Core features • User flow: email-and-password sign-up, automatic registration-fee payment (gateway is flexible—happy to hear whether PayPal, Stripe, or another reliable option fits best), and an upload panel limited to four photos plus one short video per entrant. • Admin console: full CRUD over user accounts and all uploaded media, plus a single-click purge that clears entries and user records at the end of each contest cycle. • Public gallery: a responsive thumbnail grid that shows every submitted video; clicking a thumb should launch the clip in a lightbox or simil...
