Summary

Rockstar🎓
Top SchoolSergii Glushchenko is a seasoned software engineer with 14 years of experience building high-performance databases, distributed systems, and platform infrastructure across companies from Sun Microsystems to Cloudflare and AWS. Based in Amsterdam, he combines deep systems-level expertise (Lustre, cluster filesystems, storage engines) with modern Rust development—contributing to notable open-source projects like Apache Arrow's Rust implementation and SurrealDB. He has repeatedly shipped core components for databases and observability platforms, including work on Aurora Limitless and embedded key-value engines, and has a strong track record in test automation and lint-driven code quality. Sergii moves fluidly between low-level C/C++ and contemporary Rust/Go stacks, plus CI/CD and SRE responsibilities, making him effective at both building and operating complex platforms. A pragmatic problem solver, he often focuses on maintainability improvements (enabling and fixing clippy lints, expanding tests) that reduce long-term operational risk.
