My role Blockchain and backend development

Selected contributions

  • Integrated Java and Web3j services with private Besu nodes through JSON-RPC.
  • Worked on signed transactions, contract events, receipts and transaction status monitoring.
  • Implemented pay-in, pay-out, settlement, chargeback and role-controlled contract interactions.
  • Synchronized transaction records with application data and MIS dashboards, and investigated on-chain activity using Blockscout.

Architecture

  • Hyperledger Besu and Solidity provide the blockchain and contract layer.
  • Java and Web3j connect application services to the ledger.
  • Node.js and PostgreSQL are part of the supporting application stack.
