PROFILE
Kirill Anisimov
Konstantin worked on the apache/ignite repository, focusing on backend development and technical debt reduction over four months. He removed deprecated APIs and refactored the query management subsystem, simplifying execution flows and improving maintainability. Using Java, Maven, and C++, he upgraded dependencies such as Apache Curator and ZooKeeper to enhance stability and support FIPS mode. Konstantin also modernized session management by updating Jetty and Tomcat, centralized dependency management, and improved logging consistency. His work included resource cleanup for thin client connections and migration to Mockito 5, resulting in more robust testing and reduced maintenance overhead across the Ignite codebase.
