Top SchoolIvan Zhelyazkov is a Senior Solidity Engineer with a decade of software experience, currently building smart contract systems at Bancor from Sofia, Bulgaria. He has a strong DeFi track record—leading development of xToken’s Uniswap V3 liquidity management strategies (including the xU3LP strategy that reached ~$25M TVL) and terminal-mining contracts. Formerly at Nexo and Jarvis Edge, he combines on-chain Solidity expertise with off-chain blockchain APIs in Node.js and cross-chain exposure including Bitcoin, BSC and Tron. Comfortable with low-level C/C++ and embedded systems early in his career, Ivan brings systems thinking to secure, production-grade smart contracts and protocol engineering.
