Hello!
I am interested in your offer to create a full-stack application.

Hello!
I am a Full Stack Developer with experience in integrating Web3 functionality (including MetaMask, WalletConnect, Binance Smart Chain, and NFT modules) and building decentralized applications from scratch.

I have carefully studied Predify — an on-chain prediction market operating on BNB Chain, and I understand the architecture of such systems:

Connecting Web3 wallets (MetaMask, WalletConnect, Phantom)

Interactions with smart contracts (ethers.js / web3.js)

Authorization via wallet and managing token balance

Creating and trading prediction markets with on-chain verification

Integrating backend logic (Node.js / Express / FastAPI) and React frontend

I can implement a similar project — from API architecture and working with contracts to connecting UX for betting, displaying results, and rankings.
I work with BNB Chain, Polygon, Ethereum, and I am familiar with smart contract interaction patterns through RPC and event listeners.

I am ready to start working on the task immediately.
I use clean, documented code and a modern stack (React, TypeScript, Node.js, Prisma, Web3.js / Ethers.js).
If necessary, I will provide deployment and CI/CD (Docker + Vercel + Railway + Hardhat).

I would be happy to discuss the project details and start implementation today. Expand

Message me privately "I want MVP"

Budget: 1000 USD Deadline: 15 days

Hello,

I’m a full-stack developer experienced in building web platforms similar to Predify, combining modern front-end interfaces with blockchain-based integrations. I work primarily with React / Next.js, Tailwind, and Node.js / NestJS for API and back-end development, and have hands-on experience connecting dApps to Web3 wallets using Ethers.js and Web3.js on BNB and Ethereum chains.

I can design and implement the full system — from wallet authentication, market logic, and smart-contract interactions to ranking, rewards, and admin dashboards — ensuring a responsive UI and secure architecture.

Let’s discuss your feature priorities and timeline so I can prepare a clear milestone plan and cost estimate.

Best regards,
Jeo Vincent Carretas
