Rockstar🎓
Top SchoolSerg Metelin is an experienced software leader and developer advocate who has spent two decades building products, teams, and developer communities across consumer, B2B, fintech, and blockchain. He currently leads Developer Advocacy for the Americas at Hedera/Hashgraph, translating developer signal into product direction and helping builders ship high-impact on-chain solutions like asset tokenization and climate finance. Previously he built the global DevRel function at Block.one for EOSIO and contributed to core open-source blockchain components, illustrating a rare blend of hands-on engineering and platform strategy. Serg is equally comfortable in a pull request, a product roadmap, or the keynote stage, and he obsessively focuses on the moment a developer’s first transaction lands on-chain. A Global MBA holder and award-winning founder, he also contributes to Jekyll-based Hedera proposal tooling and has experience scaling a social app to millions of users—evidence of both technical depth and growth instincts.
