During January 2025, Bartłomiej worked on the MrCin23/IO repository, focusing on secure and scalable report generation for donor management. He implemented JWT-based authentication to ensure that backend controllers generate reports using authenticated user data, removing direct user ID fetching and improving security. Bartłomiej enhanced the donor reporting UI by adding financial data, date-range filtering, and a dedicated report button, while also integrating role-based internationalization. His work involved refactoring both backend and frontend components using Java, TypeScript, and React, resulting in reusable abstractions that support maintainability and lay the foundation for future reporting features with reduced technical debt.

January 2025 (Month: 2025-01) focused on security-hardening of report generation, UI enhancements for donor reporting, and backend refactors to improve reusability and maintainability. Delivered JWT-based authentication integration for report generation, expanded donor reports with date-range filtering and financial data, and implemented i18n and UI refinements, laying groundwork for scalable reporting features.
