Summary
👤
SeniorIgor Artamonov is a London-based founder and engineering leader with 15 years of experience building distributed systems, blockchain clients, and data-processing platforms. He founded Emerald, a consumer-focused cryptocurrency wallet, and previously led ETCDEV where he assembled and guided a 14-person remote team to advance core Ethereum Classic infrastructure including clients, a VM, and developer tooling. A hands-on engineer, Igor has contributed test fixes and consensus-level changes to high-profile open-source Ethereum clients (go-ethereum and parity-ethereum), demonstrating deep practical knowledge of hard forks, ethash, and block verification. His background spans product management at Yandex and early-stage architecture work for fintech pioneers like TransferWise, giving him a rare blend of product sensibility and low-level protocol expertise. Colleagues describe him as someone who moves fluidly between shipping production-grade systems and shaping long-term tech strategy, often solving the messy integration and testing problems others avoid.
