Rockstar🎓
Top SchoolGal Rogozinski is a protocol engineer based in Tel Aviv with eight years of hands-on experience building and maintaining distributed ledger and backend systems. He spent the bulk of his career at IOTA progressing from core developer to development team lead and research engineer, contributing fixes and refactors to the IOTA reference implementation that improved hash handling, timestamps, and tangle integrity. Now at SSV Labs, he focuses on protocol-level engineering for crypto infrastructure, bringing deep practical knowledge of consensus-adjacent mechanics and production-grade backend code. His background in bioinformatics and early work in systems and Java at Mellanox and Aternity give him a multidisciplinary approach to debugging complex stateful systems. Colleagues describe him as a crypto enthusiast who prefers solving brittle edge cases and improving code structure over flashy features, which makes him especially effective on critical infrastructure projects.
