During February 2025, Ivan Tormar developed an end-to-end document chunk processing capability across the bena-sudo/rag2daw2025 and rag2daw2025frontend repositories. He designed and aligned Data Transfer Objects for chunk management, implemented a service layer with full CRUD operations, and centralized exception handling to improve maintainability and error consistency. Ivan overhauled the frontend UI using Angular and TypeScript, introducing dynamic filtering, pagination, and enhanced security routing. His work emphasized data integrity and robust API integration, addressing both backend and frontend concerns. By resolving bugs and refining database alignment, Ivan delivered a cohesive, secure, and maintainable solution for document chunk workflows.
