Summary
🤩
Rockstar🎓
Top SchoolIvaylo Kirilov is a blockchain platform engineer and open-source maintainer with nine years of experience building privacy and tooling for Ethereum clients from Java-based stacks to DevOps automation. Currently heading "Money Printing" at The Ethereum Blockchain, he previously led enterprise-grade privacy work on Hyperledger Besu and Pantheon and maintains the widely used Web3j library, adding Parity/Quorum JSON-RPC support and private transaction abstractions. Comfortable across Java, Kotlin, Solidity and CI/CD for cloud-native deployments, he has shipped Orion-based private transaction support and improved Teku's CLI/configuration UX. A frequent conference speaker and hackathon prize-winner, he combines deep protocol-level contributions with pragmatic developer tooling—often surfacing subtle integration and testing strategies (like ephemeral Orion instances) that make private Ethereum workflows reliable in practice.
