Senior🎓
Top SchoolNikolai Golub is a Senior Protocol Engineer based in Amsterdam with 13 years of software experience and a strong emphasis on Rust and backend systems. He designs and implements distributed infrastructure for blockchain protocols, having contributed to high-performance Rust Ethereum implementations like reth and production rollup scaling at ConsenSys. His background spans performance engineering, QA and full-stack product integrations—from reducing customer support churn at Booking.com to building billing and automation systems at Toptal—giving him a pragmatic, metrics-driven approach to protocol correctness and operability. Notably, he has driven compact data representations and feature-gated compression in reth, demonstrating attention to both efficiency and modularity in critical open-source code. He combines deep systems thinking with hands-on testing and automation experience, making him comfortable across the stack from low-level protocol codecs to user-facing API integrations.
