*Complete SOW attached* I am building a full-featured marketplace where owners of both residential and commercial properties can publish listings, buyers can search and signal interest, and an admin dashboard lets me review uploaded documents before anchoring each verified listing on-chain for tamper-proof proof of authenticity (NFT minting or a hash stored on a public ledger). Core user flows • Owners: sign up, complete KYC, create listings with photos, videos, and supporting documents. • Buyers: intuitive search and filtering, the ability to “favourite” or otherwise express interest in a property, and direct access to the blockchain-stamped document set once a listing is verified. • Administrators: role-based panel to inspect deeds, titles, permits, then press a single “verify” action that triggers smart-contract interaction and permanently records the proof. Technical expectations • Modern stack—React or similar front end, Node/TypeScript or comparable back end, Solidity (or Rust) smart contract, IPFS/S3 for file storage, and a mainstream chain such as Ethereum or Polygon. • Secure authentication, GDPR-compliant data handling, and audit logging baked in from day one. • Clean API so mobile apps can be added later, plus automated tests and CI/CD pipeline. Deliverables 1. Functional web application with separate owner, buyer, and admin roles. 2. Smart contract(s) with source, migration scripts, and verifiable deployment. 3. Documentation & walkthrough video covering setup, contract interaction, and future scaling. 4. Post-launch support window for bug fixes. Acceptance criteria • A test listing passes through the full flow and appears on chain. • Buyers can view the on-chain proof and associated files without exposing private data. • Lighthouse or similar audit returns no high-severity security findings. When you reply, focus on prior experience delivering Web3 marketplaces or document-verification platforms; links or brief case studies are ideal.

Hello, I can deliver a full-featured Web3 property marketplace with owner, buyer, and admin flows, including on-chain verification of listings for tamper-proof authenticity. Owners will complete KYC and upload photos, videos, and supporting documents; admins will verify listings and trigger blockchain recording via smart contracts; buyers can securely view on-chain proofs without exposing private data. I will build the platform using a modern stack (React front-end, Node/TypeScript back-end, Solidity/Rust smart contracts, IPFS/S3 storage, Ethereum/Polygon chain), with secure authentication, GDPR compliance, audit logging, and a clean API for future mobile apps. Deliverables include fully functional web app, smart contract source and deployment scripts, documentation with setup walkthroughs, and post-launch support. Acceptance criteria will ensure end-to-end listing verification, secure buyer access, and no high-severity security issues in audits. I have prior experience delivering Web3 marketplaces and document-verification platforms and can provide case studies demonstrating secure, scalable implementations.

Hello, I have reviewed the attached SOW. Your concept of combining a property marketplace with blockchain-backed document verification is very interesting, and I’d be glad to help build the full platform from architecture to deployment. I can develop a secure marketplace where property owners list assets, buyers search and express interest, and administrators verify documents before anchoring proof on-chain. The system would use a modern stack (React + Node.js/TypeScript) with smart contracts on Ethereum/Polygon, while documents are stored securely on IPFS or S3 and referenced on-chain through a hash or NFT-based verification record. The platform will include role-based dashboards (owner, buyer, admin), KYC workflow, advanced property search, favourites/interest tracking, and an admin verification system that triggers the blockchain proof. I focus on secure architecture, clean APIs for future mobile apps, and production-ready deployments with CI/CD. Lets connect to discuss this project in detail Best regards. Ajay

I see you’re building a comprehensive blockchain real estate marketplace with distinct roles for owners, buyers, and admins, plus on-chain verification of listings. Your focus on a secure, GDPR-compliant platform with smart contract integration and an admin dashboard for document verification is clear. Your requirements for a React or similar frontend, Node/TypeScript backend, Solidity smart contracts, and IPFS/S3 storage align well with a modern tech stack. The need for audit logging, clean APIs for future mobile apps, and a CI/CD pipeline reflects a robust, scalable approach to the project. I recently developed a decentralized document verification system using Solidity smart contracts and Node.js backend, integrating IPFS for decentralized storage and a React frontend for user roles. The platform included secure KYC flows, admin verification, and blockchain anchoring of documents, ensuring tamper-proof records and smooth user experience. This directly matches your need for verified listings anchored on-chain with clear role separation. I can deliver a fully functional marketplace with smart contracts and documentation within 6 weeks. Let’s discuss your priorities and next steps to ensure the platform meets your goals precisely.
