Summary

Rockstar🎓
Top SchoolAlexey Shekhirin is a software engineer with 11 years of experience building backend systems, developer tooling, and blockchain infrastructure from London. He has shipped production services at startups and scaleups—spanning Go microservices, Kubernetes, Kafka, Postgres, and cloud-native observability—and later focused deeply on Rust-based Ethereum tooling. A prolific open-source contributor, Alexey improved core components of high-profile projects like ethers-rs, reth, revm and Solang, driving ABI/parser correctness, storage and EVM improvements, and performance-focused refactors. He pairs pragmatic product delivery (notifications, rewards, and auth systems) with low-level systems work, and has a track record of improving CI, fuzzing, and gas accounting for developer tooling. Colleagues know him for turning subtle protocol and parsing edge-cases into robust, well-tested code and for comfortably straddling full-stack product needs and cryptographic/blockchain internals.
