• Build backend services for:
  • Transaction validation & event listening
  • On-chain status tracking
  • Storing blockchain data (orders, payments, refunds)

Smart Contracts

• Design and develop Solidity smart contracts (payments, escrow, loyalty NFTs, discounts, etc.).
• Deploy contracts to Ethereum or EVM-compatible networks (BNB Chain, Polygon, etc.).
• Ensure gas optimization, audit security, and best practices.

Security & Reliability

• Implement protections against signature replay, double spending, and other common vulnerabilities.
• Manage RPC communication, gas monitoring, and transaction lifecycle troubleshooting.

Collaboration & Documentation

• Work closely with React and Django engineers to integrate Web3 logic with backend APIs.
• Write clear technical documentation for Web3 endpoints, smart contract architecture, and integration flows.
