Alexander Papageorgiou is a blockchain security leader with eight years of hands-on experience in smart contract auditing, protocol design, and secure Golang/Cosmos-SDK development. As Head of Security Services at Omniscia and Head of Judging at Code4rena, he combines technical rigor—especially in Solidity optimization—with process and tooling design to scale high-quality audit workflows. He has led and reviewed audits for DeFi primitives, bridges, and NFTs, authored EIPs and optimization PRs, and built bespoke toolkits he plans to open-source. Comfortable across full-stack and systems languages, he prizes simplicity as security and applies that principle from low-level EVM gas optimizations to contest UX and governance. Based in Athens, Greece, he blends academic study in informatics with entrepreneurial product work dating back to multisig wallet protocols and novel tokenization systems.
