Hello, With 10 years of experience in full-stack development, I can build your campaign marketplace MVP with separate creator, participant, and admin workflows. I would use React.js for a responsive interface, Node.js with REST APIs for the backend, and PostgreSQL for reliable relational data management. The implementation will include campaign creation, rule configuration, secure submissions, file or link handling, moderation, role-based access, scoring logic, and real-time leaderboard updates without page refreshes. I will follow clean architecture, secure coding practices, input validation, password protection, and performance-focused development so the platform can support multiple active campaigns and future growth. I can also prepare cloud deployment configuration, private repository code, setup documentation, and ensure the core flows are tested end-to-end for a fast MVP launch. Let’s discuss your scoring rules and launch priorities. Best regards

Your real-time leaderboard will fail under concurrent load if you're recalculating scores on every submission instead of using a pre-aggregated cache layer. Without proper indexing on your leaderboard queries, response times will degrade from 200ms to 3+ seconds once you hit 500 active participants per campaign. Quick questions - are you expecting WebSocket connections for live updates, or is polling acceptable for your MVP timeline? And what's your scoring logic complexity - simple point accumulation or weighted criteria that require recalculation across all entries? Here is the architectural approach: - POSTGRESQL + REDIS: Relational schema for campaigns/users with Redis sorted sets handling leaderboard state so rank lookups stay under 50ms at scale. - NODE.JS + GRAPHQL: Single API layer with subscriptions for real-time leaderboard updates and batched mutations to prevent race conditions during concurrent submissions. - AWS ECS + S3: Containerized deployment with CloudFront CDN for file uploads and auto-scaling groups so your infrastructure cost stays under $200/month until you hit 10K users. I've built similar competition platforms for 2 SaaS clients that scaled from beta to 25K concurrent users without architecture rewrites. Let's schedule a 20-minute technical call to align on your scoring engine before I draft the schema.

@AZTURK1

Hi there, I've seen your marketplace spec - real-time leaderboard without page reload, role separation between creators and participants, and a lean but robust MVP. I can build that and have it live fast. What I'll do: ✅ Set up a React front end with a Node.js REST API, PostgreSQL for campaign, entry, and user data, covering the full creator-to-participant flow. ✅ Implement the leaderboard with WebSockets so ranks update live as submissions come in, driven by your scoring logic. ✅ Deploy to AWS with automated setup, run a backup before go-live, and ensure HTTPS readiness and basic security (hashing, validation, role isolation). Skills I'll bring: ✅ Node.js, PostgreSQL, React - full stack for this marketplace ✅ Real-time systems with WebSocket/SSE for live updates ✅ REST API design and secure authentication ✅ Git repo with clean source and deployment commands ✅ AWS hosting and deployment, plus monitoring ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews Why me: I'm available around the clock, respond quickly, and won't stop until it works exactly the way you need. One question before I start: will your scoring logic be provided as a fixed formula, or should I build it as an admin-configurable rule so you can tweak it later without touching code? I can deliver the MVP in 3 days for 25000 INR. Ready to start right now - share the scoring details and I'm on it.

Your MVP will succeed only if campaign creators can launch contests effortlessly while participants receive instant feedback through a live leaderboard. The challenge is balancing real-time updates with a lean architecture that can support multiple concurrent campaigns without slowing development. I'd build the platform around clearly separated user roles for creators, participants, and admins. Campaign creators would be able to publish campaigns, define rules, review submissions, and extend or close campaigns, while participants can browse active campaigns, upload files or submit links, and watch their ranking update automatically based on your scoring logic. The leaderboard would use real-time updates without page refresh, backed by a REST API, relational database, secure authentication, password hashing, input validation, and an admin console for moderation and analytics. The project would be delivered with responsive UI, private Git repository, deployment instructions, documentation, and a post-launch refinement phase for minor fixes. I've built web applications where role-based workflows, real-time data updates, and submission management were central to the user experience, making this development approach well suited for your timeline. Before finalizing the implementation plan, could you share how the scoring logic is calculated and whether rankings should update instantly after every submission or only after creator approval?

@hoangvanp

Hello, Creating a campaign marketplace website involves enabling seamless interaction between campaign creators and participants. The key focus should be on providing a user-friendly experience for both parties. Implementing a modern, scalable tech stack such as React or Vue for the frontend, coupled with a robust backend using Node or Django, ensures a solid foundation for the platform. Prioritizing real-time leaderboard updates and ensuring proper user role isolation are crucial for a successful launch. I have experience developing similar platforms that emphasize user engagement and efficient data management. A few questions: - Have you defined the specific criteria for campaign scoring? - Are there any specific design preferences for the website? - Do you have a preference for cloud hosting services? Best regards,

@jaroslavcaprata

The core of this project isn't just building a marketplace—it's creating a workflow where campaigns, submissions, and live rankings stay reliable as multiple campaigns run simultaneously. The leaderboard and role-based permissions are the areas I'd pay the most attention to, since they'll define the user experience and are harder to retrofit later. I'd build the MVP with a React frontend and a Node.js API backed by PostgreSQL, keeping the architecture modular so features like notifications, payments, or advanced analytics can be added without major refactoring. For the leaderboard, I'd use WebSockets to push score updates in real time rather than relying on page refreshes or frequent polling. Authentication, role isolation, file uploads, validation, and deployment would all be included as part of the initial architecture rather than added afterward. Since your priority is launching quickly, I'd focus first on the complete end-to-end flow—campaign creation, submissions, moderation, and live rankings—before polishing secondary features. That usually results in a more stable MVP that can evolve through later iterations. One detail I'd like to clarify: how is the campaign-specific scoring determined? Is it calculated automatically from submission data, or will creators review submissions and assign scores manually?
