PROFILE

Mikhail Lukyaniuk

Mikhail Lukyaniuk contributed to the geoserver/geoserver and geotools/geotools repositories by driving modularization, dependency hygiene, and backend migration initiatives. He removed the H2 datastore extension, established a migration path to supported datastores, and migrated database backends to GeoPackage, improving long-term maintainability and data interoperability. Mikhail enhanced modularity by refactoring KML and WCS modules into extensions and introduced a plugin system for raster formats. He also upgraded dependencies such as Gson and Protobuf, refactored JSON parsing, and eliminated unused libraries to streamline builds and reduce security risks. His work leveraged Java, Maven, and XML configuration for robust backend development.
