Senior🎓
Top SchoolJihed Chalghaf is a Lead Offensive Security Engineer with eight years of experience securing decentralized systems through smart contract auditing, protocol analysis, and adversarial research. He blends hands-on smart contract development (Solidity, Rust, Move) with attacker-minded reviews, having led 30+ assessments that uncovered 40+ critical vulnerabilities across Layer-1s, bridges, DEXs, lending protocols and developer SDKs. Jihed has ported major DeFi primitives to Casper, driven end-to-end audits for mainnet launches, and builds internal knowledge programs to raise team security maturity. He also experiments with agentic AI workflows and multi-model orchestration to automate repetitive audit tasks—an uncommon bridge between offensive security and automation.
