Build Standalone Showcase or leaderboard Microservice with Voting, Moderation, and Admin Panel

Overview:
I am looking for a developer to build a standalone Showcase microservice for my platform. The module should support project submissions, user voting, automatic cycle-based rankings, content moderation using OpenAI, an admin panel for control, and a front-end ad placement block. It must be clean, lightweight, and responsive on both desktop and mobile devices.
You will not receive access to my main Laravel/Angular/Java platform. This module must be deployed separately and connected via API. I will provide server access, OpenAI API key, and my brand color scheme.
What the Module Should Include:
1. Public-Facing Frontend
• Project submission form with:
o Project name, tagline (60 characters max), URL
o Uploads: logo (500x500px, 15MB), up to 6-8 cover images, optional video
o Collaborators (text or tags), tech stack tags, project category, long description, fields to list features, field to list benefits
o Optional project completion percentage tracker
• Voting system:
o One vote per user per project or cycle
o Vote count visible
o Leaderboard sorted by popularity with top 3 rankings
o New cycle begins every 14 days
• Voting cycle:
o Countdown timer
o Automatic cycle close and winner selection
o Historical cycle records stored and viewable
• Sponsored ad slot:
o Dedicated area on leaderboard or sidebar for a static banner or embedded featured content
o Configured and managed from admin panel
o Should not interfere with vote logic
• UI/UX expectations:
o Clean, minimalistic, responsive layout that works across mobile and desktop
o Designed by you based on my branding colors
o Use Bootstrap, Tailwind, or Material (or similar) to keep it light and fast

2. OpenAI Moderation Integration
• Use OpenAI Moderation API to scan project name, tagline, and description
• Automatically flag inappropriate content (hate, violence, adult, spam, political)
• Hold flagged content for admin review
• Display moderation logs in admin panel
• Allow threshold adjustment

3. Admin Dashboard
• Secure login
• View all projects and submissions
• Review flagged projects and approve, reject, or edit
• Control the ad slot content
• Force cycle close and assign winners
• Filter or search by user, project, tag
• Fully usable on both mobile and desktop browsers

4. API Endpoints
• POST /projects: Submit new project (OpenAI moderation triggered)
• GET /projects?user_id=xxx: List all user projects
• POST /votes: Cast a vote
• GET /leaderboard: Ranked project list
• GET /timer: Get remaining time in voting cycle
• POST /cycle/close: Manually end voting cycle and assign winners
• GET /winners: List historical winners
• GET /ad-slot: Fetch current ad slot content
• POST /admin/ad-slot: Update ad slot from admin
• GET /admin/projects: View/manage projects in admin
• GET /admin/moderation-logs: View OpenAI moderation flags
• Include if any missing.
