Al-Jazaeri

Senior Web3, Smart Contract & Async Systems Engineer focused on blockchain architecture, high-performance automation, and security. I build production-grade dApps, gas-optimized Solidity smart contracts, and low-latency trading/monitoring tools. Core Competencies: 1. Smart Contracts & DeFi: • Solidity architecture (ERC20, ERC721, Vaults, State Machines). • Foundry/Hardhat testing, Reentrancy protection & EVM gas optimization. 2. High-Performance Automation: • Async Python engines (Asyncio, Aiohttp, WebSockets) for 24/7 VPS uptime. • Real-time EVM event tracing, router bypass (Transfer log decoding), and self-healing RPC reconnections. 3. Full-Stack Web3: • Responsive frontends with Next.js, React & TypeScript. • Wallet integration via Wagmi, Viem, Web3Modal & Ethers.js. I prioritize clean architecture, institutional security, and official Escrow milestones. Let’s build reliable Web3 solutions together!
