Summary
👤
SeniorAlexandr Biryukov is a Solidity developer with 12 years of engineering experience and a decade-plus focus on blockchain and trading automation across CeFi, DeFi, stocks, options and NFTs. Active in Ethereum since 2017, he builds and audits smart contracts and staking primitives (liquid staking, batch deposits, payment splitters, staking NFTs, account abstraction) using Solidity, Yul, Hardhat and Foundry, and has led AMM and MasterChef-style development for PancakeSwap-like ecosystems. His background spans full-stack and middleware systems—fraud monitoring for banking, Web3 admin UIs, and data gathering from The Graph—bringing production-grade architecture and on-chain tooling experience. A PhD-trained researcher who worked on blockchain applications at Notre Dame, he also enjoys legacy and alternative chains (Steem, Hive) while learning Aptos, Move and Rust, reflecting a pragmatic curiosity that bridges research and deployable DeFi systems.
