Full Prototype Build - Dashboard, API & Web3 Pipeline (3-Day Sprint)

I’m launching a fast-moving prototype effort and need three individual developers (not a team) to work
in parallel on separate components of a small but high-impact demo. This is a 3-day sprint to build a
clickable prototype for InsightBridge, a hybrid analytics concept that merges subscription metrics with
real Web3 wallet intelligence.
Each developer will own their part end-to-end and collaborate with me directly. You will not be required
to coordinate with the other freelancers — I’ll manage integration.
What the prototype must deliver:
This prototype demonstrates a simple but complete data pipeline:
Web3 → Backend API → Dashboard UI
I am hiring THREE different developers for three distinct roles:
1. Frontend Developer (React / Next.js / Tailwind)
- Build a responsive dashboard UI
- Pages: Overview metrics, Subscription analytics, Wallet insights
- Integrate REST API
- Implement MetaMask/WalletConnect
- Deliver polished UI
2. Backend Developer (Node.js / Express / PostgreSQL)
- Build REST endpoints for metrics
- PostgreSQL schema + seed data
- API for revenue, subscribers, churn
- Proxy Web3 data from blockchain service
- Lightweight auth
3. Blockchain Developer (Ethers.js / Web3.js)
- Wallet balance lookup
- Recent transaction history
- Optional contract read
- JSON output for backend
How work will happen:
- Direct 1:1 communication with me
- No coordination with other freelancers
- I handle integration
- Fast iteration due to 3day timeline
Purpose:
InsightBridge will evolve into a full analytics suite blending subscription intelligence with on-chain
financial data. This prototype validates core UX and functionality for partners and investors.
Skills Required:
Frontend: Next.js, React, TailwindCSS
