Summary
👤
SeniorSergey Ratiashvili is a Senior Blockchain Engineer and Tech Lead with 11 years of backend and distributed-systems experience, now focused on designing DeFi infrastructure and cross-chain architectures. He builds production-grade smart contracts and off-chain services across Cosmos, Solana, and EVM ecosystems, emphasizing correctness, security, and fault tolerance. Sergey has led protocol-level decisions for liquid staking, oracle-driven vault mechanics, and interchain integrations, often owning system design end-to-end. His hands-on fluency in Rust, Solidity, TypeScript, and Go underpins pragmatic architecture choices that balance long-term maintainability with operational readiness. Based in Novi Sad, he’s progressively shifted from coding and incident response toward technical leadership while still preferring to solve the hardest engineering challenges himself. An engineer who bridges on-chain logic and backend realities, he brings rare cross-ecosystem depth to complex DeFi primitives.
