I need a mobile-responsive web app that lets visitors sign in through the Steam API, automatically pulling their SteamID so they can enter free sweepstakes with a single click. The core build should feel snappy on phones first, then scale gracefully to desktop. Key flow • User arrives, taps “Sign in with Steam,” and is authenticated via OpenID. • Once logged in, the site tracks each entry they make, stores it under their account, and presents a simple profile page that shows only their sweepstakes history. Sweepstakes engine An automated job must close each giveaway at the scheduled time, randomly select a winner from valid entries, and fire off both an on-site and email (or Steam message if feasible) notification. I also want an admin view where I can start a new giveaway, specify the end date, and see live entry counts. Monetisation Video ads are the sole revenue stream, so placements need to be integrated without tanking load times or breaking the mobile layout. Pre-built ad tags will be supplied; just leave reliable hooks and test that they don’t interfere with sign-in or drawing winners. Preferred stack I’m open, but a modern JavaScript framework (React, Vue or Svelte) on the front end and a lightweight Node or Python back end with a relational database feels right. Security, rate-limit protection on the Steam API and clean code comments are expected. Deliverables • Fully deployed, mobile-first web app with Steam login, entry tracking, automated winner selection and winner notifications live on a test subdomain • Source code in a private Git repo with a concise README for local setup • Brief hand-off session (recorded or live) walking through the admin panel and cron/worker configuration If you’ve shipped Steam-integrated projects before or have a strong grip on OAuth/OpenID flows and responsive UI, this should be a straightforward build. Let me know the framework you’d choose and any similar work you can show.

Hello, I understand you want a mobile-first Steam sign-in web app with OpenID, entry tracking, admin for giveaways, automated winner selection, and ads integrated without hurting performance. I propose a React front-end with a Node.js backend and PostgreSQL for clean, scalable code. The app will be mobile-first, with a responsive layout, fast OpenID Steam login flow, and a concise user profile showing sweepstakes history. The sweepstakes engine will run a scheduled job to close giveaways, pick a random valid entry, and notify winners on-site and by email/Steam message when possible. Admin panel will show live entry counts and allow starting new giveaways with end dates. Ad tags will be loaded lazily to keep load times snappy. A test subdomain will host the deployable app, and I will provide a private Git repo with a README for local setup and a brief hand-off session. What framework would you prefer for the frontend (React, Vue, or Svelte), and are there any specific Steam OpenID libraries or email/Steam notification preferences I should align with? Best regards,

Hi, this is Elias from Miami. I went through your spec and the flow is clear: mobile-first sweepstakes web app with “Sign in with Steam” (OpenID), auto-capture SteamID, 1-tap entries, profile page showing only entry history, plus an admin panel to create giveaways + see live counts. Then a scheduled job closes the giveaway, randomly selects a winner from valid entries, and sends on-site + email notifications (Steam message only if it’s realistically supported without brittle workarounds). Video ad tags get reliable placements/hooks without slowing mobile or interfering with login/draw. Additionally, I have a few questions: Q1: Is eligibility strictly “one entry per Steam account per giveaway”, or do you want multiple entries (e.g., daily entries / bonus entries)? Q2: For winner selection, do you need provable fairness (public seed/hash + timestamp) or is standard secure RNG + logged draw acceptable? Q3: Ads: where exactly do you want placements (pre-roll before entry click, between feed sections, footer sticky), and should entry be allowed if an ad blocker prevents the tag from loading? Previous work: I’ve shipped mobile-first web apps with third-party auth (OAuth/OpenID), admin dashboards, scheduled jobs/queues, and high-traffic event flows with anti-abuse protections. Looking forward to hearing from you. Regards, Elias

Hi I can build a mobile-first sweepstakes web app integrated with Steam OpenID so users can sign in instantly, pull their SteamID, and enter giveaways with one tap. A key technical challenge is securing the OpenID flow while preventing abuse of the Steam API, and I solve this through strict rate limits, server-side validation, and clean token handling on a lightweight Node/Python backend. Your sweepstakes engine will track entries per user, auto-close giveaways on schedule, randomly select a winner, and trigger on-site + email notifications. An admin panel will let you launch new giveaways, set end dates, and monitor live entry counts. Ad integration will be handled with reliable hooks so video ads don’t impact layout, login, or winner selection. I’d use a modern framework like React or Svelte for a fast, responsive UI and clean component structure. Thanks, Hercules

With extensive experience in developing mobile-responsive web applications, I previously built a gaming platform that integrated Steam's API for user authentication and giveaways.

For the tech stack, I would lean towards React for the front-end and Node.js for the back-end, as both frameworks offer efficiency and scalability. I’d love to discuss your project further!
