The Vision

At Avin Avisa, I built a peer-to-peer cryptocurrency trading platform that allowed users to trade directly with each other, without a centralized exchange. This required implementing atomic transactions, blockchain integration, and real-time order matching.

Key Features

  • P2P Trading - Direct user-to-user transactions

  • Atomic Transactions - MongoDB transactions ensure data integrity

  • Blockchain Integration - Ethereum integration via Web3.js

  • Real-Time Order Book - WebSocket-based order matching

  • Secure Wallet Management - Encrypted private key storage

    • Technical Highlights

  • Node.js + TypeScript - Type-safe backend development

  • MongoDB Transactions - Atomic multi-document operations

  • Web3.js - Ethereum blockchain integration

  • WebSocket - Real-time order book updates

  • Docker - Containerized deployment

    • Results

  • Transaction Success Rate: 99.8%

  • Trade Execution Time: < 200ms

  • Zero Data Loss: All transactions atomic

  • Users: 10,000+ registered users

  • Trade Volume: $2M+ processed

    • Impact

    The platform successfully enabled P2P cryptocurrency trading with high reliability and security, processing millions of dollars in trades.
