Summary
🤩
Rockstar🎓
Top SchoolAlexandr Vlasov is a Montreal-based blockchain engineer with 11 years of experience building backend systems and cryptographic primitives for Ethereum scaling projects. He has contributed to high-profile open-source work at Matter Labs on zkSync—implementing elliptic-curve "baby jubjub" routines, transfer circuits, and a rescue hash—and improved Solidity compilation tooling via a hardhat zkSync plugin. His cross-platform contributions include enhancing web3swift with ERC20/ERC721 support, EIP-681 parsing, and keystore performance optimizations. Trained as a physicist and PhD electrical engineer (MSU and McGill), he blends deep mathematical intuition with practical engineering to tackle complex cryptography and protocol-level problems. Colleagues note his knack for translating research-grade crypto into production-ready build and test improvements that reduce friction for other developers.
