Senior🎓
Top SchoolAlexander Slesarenko is a Senior Technical Architect with over 25 years in software development and 16 years of focused professional experience building robust, protocol-level systems, currently leading a Rust-based cross-chain protocol project for IOHK/Polkadot. He blends hands-on engineering with technical leadership—managing small teams, delivering proofs-of-concept, and designing DSLs such as a Rust query language for Ethereum’s Merkle Patricia Trie to enable trust-minimized data access. A longtime core developer and co-founder at ergoplatform.org, he has contributed to blockchain clients like Ergo and Scorex, with practical expertise in serialization, binary data handling, state management, and migration to modern cryptographic libraries. Comfortable moving between low-level protocol details and system architecture, he emphasizes scalability, security, and maintainability in distributed systems. Based in Cambridge with a background in applied mathematics, he has a track record of turning complex cryptographic and storage concepts into pragmatic engineering solutions.
