Rockstar🎓
Top SchoolKirill Bulatov is a pragmatic software developer based in Turku, Finland, with roughly a decade of hands-on experience building backend systems, developer tools, and databases. He’s a Rust-focused full-stack engineer who has contributed to high-profile open-source projects like rust-analyzer, the Rust VSCode extension, and Neon’s serverless Postgres, bringing deep familiarity with language-server features and database internals. Kirill has shipped production services and tooling across startups and product teams—from collaborative editor work at Zed to scalable Postgres infrastructure at Neon—while also improving IDE UX through inlay hints, code lenses, and TOML support. Comfortable across Java, Python and modern Rust backends, he gravitates toward projects that value craftsmanship and knowledge sharing, often improving observability and developer ergonomics behind the scenes. Collected experience in performance-sensitive, system-level programming gives him a pragmatic edge when debugging complex runtime and I/O issues.
