Kirill Nesmeyanov is a senior PHP engineer and open-source maintainer from Moscow with 13 years of experience building high-performance web systems and developer tooling. He is the author of several notable PHP projects (Railt GraphQL Framework, RoadRunner, phplrt, boson-php) and serves on the PHP Russia / Highload++ program committee, bridging community leadership with hands-on engineering. His background spans backend systems at RAMBLER&Co and Spiral Scout where he combined library development, advocacy, and test automation to improve reliability and developer experience. Kirill contributes to widely used projects such as JetBrains/phpstorm-stubs and cycle/orm, bringing deep familiarity with FFI, ORMs, JVM-based PHP implementations and performance-critical infrastructure. Equally at home refactoring core framework tests or adding Swing bindings to a Java-based PHP runtime, he brings a pragmatic, cross-language perspective that surfaces non-obvious tradeoffs between developer ergonomics and runtime performance.
