Protocol Engineer at Inco
Cyprus
Summary
👤
Senior🎓
Top SchoolGiorgos Kourtellos is a Protocol Engineer with a decade of engineering experience and a deep focus on blockchain systems since 2017, blending mechanical and renewable-energy academic training with hands-on smart contract and full-stack Web3 development. He has led architecture and development teams—serving as CTO and Head of Development—and shipped production Solidity contracts, upgradeable proxy patterns, and user-facing dApps using TypeScript, React, Next.js, Hardhat, Foundry, and TRPC. Giorgos brings a problem-first mindset, favoring rigorous analysis and practical, auditable solutions that prioritize security, UX for non-Web3 users (including ERC4337/Account Abstraction proofs of concept), and real-world adoption. Currently driving protocol work at Inco after senior roles building scalable dApp stacks at Nudge.xyz and game-focused blockchain systems at OwnPlay, he pairs product-facing thinking with low-level protocol design. Based in Cyprus, he combines academic research experience in renewable systems with a rare mix of R&D, devops-minded deployments (Supabase/Vercel), and stakeholder-facing communication.
