    Trophy icon Lightweight Discord Link Monitor
    3 días left

    A single-purpose Discord bot is all that is needed. It should pull a dynamic list of 2000-5000 URLs from a standard Google Sheets document, then—running on a small DigitalOcean droplet—cycle through those links every two to three minutes. For each check the bot must load the page and confirm that expected content is present; if the page renders correctly the bot marks it “Active,” otherwise it flags it “Inactive.” Whenever a status changes, or on every poll if you prefer the simpler approach, the bot must post an individual message for each URL inside a designated Discord channel. Messages can be edited in place or sent anew, so long as they stay easy to read at a glance. Please build with reliability in mind: graceful handling of rate limits, reconne...

    I need a seasoned Laravel developer who can jump in immediately and push a round of front-facing, checkout, and admin updates over the finish line. Scope • Home page overhaul – a fresh layout plus updated copy and visuals that match our current brand guidelines. • Creation of a few new static pages that follow the same styling standards. • Checkout flow adjustments (templates and controller logic) to streamline the user journey and keep the existing API responses intact. • New quality-of-life features in the admin panel; Next Step Once these web changes are live, the same improvements will be mirrored in a Flutter app, so structuring the work with clear separation of view, business logic, and API layers is essential.

    I need a reliable Make (formerly Integromat) scenario that keeps Odoo and Lightspeed talking to each other without manual intervention. The priority is accurate Stock management and smooth Ordering management, so real-time updates in both systems are essential. Here is the data that must move back and forth every time a change occurs: • Product categories • Supplier information • Inventory levels Standard fields alone won’t cut it—I rely on those specific data points to control food cost and purchasing decisions. Your scenario should pull the data through each platform’s API, map it cleanly, and handle updates, inserts, and deletions so nothing drifts out of sync. Error handling, logging, and clear documentation are part of the job so my in-house te...

    I’m launching a custom football credit platform whose revenues will be channelled to charitable projects, and I need someone to turn the concept into solid, production-ready code. The core of the build is a real-time odds engine that pushes live prices straight into the user interface without lag. Automated odds updates are non-negotiable, so your solution should comfortably poll or stream data from the feed of your choice and refresh markets instantly; if you can leave hooks for future odds comparison or historical analysis, even better. Running alongside the odds module is a full agent management system. Agents drive volume on the site, so the back-office has to give them a clear view of their business while keeping my overhead light. The module must handle: • Agent registra...

    I need a straightforward Android application that lets users collect virtual coins by watching ads served through AdMob and Facebook Audience Network. Once enough coins are earned, the user chooses whether to spend them on Instagram likes, views, or followers. The moment an order is placed, the quantity selected must travel automatically to my SMM-panel account through its API so that fulfilment is completely hands-free on my side. I already have the panel; the app only has to send the right call and display real-time order status back to the user. Key flow • Show rewarded video or interstitial ad → credit coins. • Keep a running coin balance on device and server. • Let the user pick “Likes”, “Views”, or “Followers”, enter t...
