Misha Moskalenko focused on backend development and database management for the documenso/documenso repository, addressing a data accuracy issue in folder statistics. He delivered a targeted fix that excluded soft-deleted documents and templates from folder count calculations, ensuring that only active items are reflected in analytics and reports. Using TypeScript, Misha updated the findFoldersInternal query logic to refine how documents and templates are counted, reducing the risk of side effects by keeping the changes well-scoped. This work improved the reliability of business analytics and reporting, demonstrating careful attention to correctness and maintainability in the project’s backend data handling.
