PROFILE

Alexander Myltsev

Andrey Myltsev contributed to NilFoundation/nil by developing foundational backend and blockchain features, including a cross-shard transaction ID scheme and a governance contract with rollback support. He improved system reliability through targeted bug fixes, such as resolving data races and optimizing peer discovery, and enhanced build automation using Go, Solidity, and CI/CD workflows. His work included refactoring the Merkle Patricia Trie for better storage efficiency and error handling, as well as modernizing dependency management and build systems with CMake and Conan in conan-center-index. Andrey’s engineering demonstrated depth in distributed systems, concurrency, and maintainable code, resulting in improved scalability and operational stability.
