    I want a web platform that lets Murder Mystery 2 players stake their Roblox items in real-time games—coin flip, jackpot and an upgrader—modelled as closely as possible on the look, feel and flow of bloxybet.com. Coin Flip • Any number of coin-flip rooms can run in parallel. Players should be able to open a room, set the wager, share the link and wait for an opponent, or instantly join an open room. The interface needs the same fast, casino-style experience Bloxybet offers, with live status updates through WebSockets or a similar solution. Jackpot & Upgrader Both games must mirror Bloxybet’s mechanics: tier-based jackpot pools that roll on a timer, and an upgrader where players select an item, choose a percentage chance and see an animation revealing suc...

    I run on a full MERN stack and I need every order placed in my Shopify store to appear in our MongoDB in near real-time, complete with customer details, AWB assignment and live status updates back to Shopify. The flow I picture is straightforward: a webhook (or similar) fires from Shopify, your service captures it, formats the payload, then writes order and customer data into our existing collections. When the shipment moves, my system should push the new status and AWB number to Shopify so the buyer sees the update instantly. Key data points are: • Order details (items, prices, shipping method, timestamps) • Customer information (name, email, phone, address) • Two-way status synchronisation, including AWB generation/return Tech context: the site uses Node.js/E...

After installation, users log in using their mobile number via OTP authentication with auto-read and auto-fill for secure, password-free access. Users then complete a structured biodata form including personal details (name, gender – groom/bride, age, height, education, occupation, city, contact details, and family details). Based on this, the system automatically generates a biodata profile with a unique Biodata ID. Users upload 2–4 photos, after which the system automatically generates a watermark (Community Name + Biodata ID) and links it se...

    I’m building Curacare, a full-stack web app that lets people handle medical emergencies without scrambling for information. The heart of the platform is a seamless doctor-consultation flow, so the appointment-scheduling module has to feel effortless on both mobile and desktop. Alongside that core feature, users must be able to reach hospitals instantly through a dedicated “Contact Hospital” pathway—click-to-call, email, or any direct channel you suggest—surfaced within one tap from the dashboard. Speed and reliability matter more than bells and whistles: every interaction should load in under a second, and every piece of patient data must be encrypted at rest and in transit. Tech-stack choices are open, though I’m leaning toward a React front-end, ...
