During October 2025, Guner worked on the cube-js/cube repository, focusing on enhancing the scaffolding schema to improve numeric type mapping. By extending support for additional numeric data types and ensuring they consistently map to the 'number' type, Guner increased compatibility and data integrity across data sources. The work involved implementing regression tests to verify case-insensitive mappings and correct numeric behavior, as well as addressing missing numeric types in the schema-compiler. Using TypeScript and full stack development skills, Guner validated the changes across repositories, resulting in more reliable schema generation and reducing the likelihood of runtime type errors in production environments.
