👤
Senior🎓
Top SchoolArthur Galiullin is a software engineer based in Warsaw with 10 years of experience building full-stack and blockchain systems, currently developing Solidity and smart-contract infrastructure at Overlay Protocol. He previously led protocol-level work at KUMO—rewriting lending mechanics, integrating Chainlink and Tellor feeds, and implementing upgradeability patterns like Diamond and UUPS—bringing deep EVM, Hardhat, and OpenZeppelin expertise. Earlier in his career he honed backend and API skills on Ruby on Rails projects, migrating monoliths to SPA+API architectures, improving performance, and automating CI/CD for international clients. Arthur combines pragmatic product-minded engineering with low-level smart-contract rigor, able to jump between Rails APIs and audited Solidity codebases. He holds a master's in Computer Software Engineering and often pairs production-facing work with custom tooling (Hardhat tasks, bespoke tests) to maintain safety and deployability.
