Summary
👤
Senior🎓
Top SchoolMario Karagiorgas is an Architect in Web3 Engineering with 10+ years of systems and blockchain experience, currently building cross-chain liquidity, wallet messaging, and chain-abstracted DeFi at Rainbow while co-founding a stealth RWA lending startup. He blends hands-on layer-1 development in Go, Rust and Solidity with applied cryptography (ECDSA, MPC, Ed25519) to deliver single-signature cross-chain protocols and efficient userOps. Mario has led design and implementation of ERC-4337-based Intents, bundlers and smart accounts, and has production Cosmos node and mainnet validation experience including Rust IBC work. His background ranges from custodial wallet optimizations and MPC key sharding to distributed AWS Kubernetes services and event streaming, showing fluency across infrastructure and protocol layers. Summa Cum Laude MSc in Digital Currencies underpins his academic rigor, while lesser-seen strengths include a musician’s precision—he enjoys tactile keyboards and noisy instruments, reflecting a hands-on, detail-oriented engineering style. Based in Greece, he is an active open-source contributor focused on practical, auditable blockchain primitives and cross-chain UX innovations.
