Martin Trajanovski developed and maintained core features for the SciCatProject/scicat-backend-next and SciCatProject/frontend repositories, focusing on robust data management, access control, and dynamic user interfaces. He engineered dynamic Material tables with Angular and TypeScript, enabling server-side pagination, persistent user settings, and advanced filtering for datasets and files. On the backend, Martin enhanced API endpoints, implemented granular group-based permissions, and led DataCite metadata migrations to support evolving publishing standards. His work included schema migrations, state management with NgRx, and comprehensive test coverage, resulting in scalable, secure, and maintainable systems that improved data integrity, user experience, and operational reliability.

September 2025 (2025-09) performance summary for SciCat projects. Delivered end-to-end DataCite v4.6 migration across backend and frontend, unlocking a migrated published data model, existing data migrations, and updated configuration. Implemented dataset filtering enhancements and user settings migration to improve accuracy and flexibility. Launched dynamic data publishing and metadata management in the frontend with full CRUD, persistence, unsaved-changes guards, and batch editing, aligned with new DataCite metadata fields. Unified filtering architecture for datasets and proposals across dashboards to improve consistency and maintainability. Overall, these efforts improve data governance, user experience, and time-to-value for data publishing and discovery. No major bugs were reported; stability was enhanced through schema migrations, improved filters, and guard logic.

July 2025 - SciCatProject/frontend: Delivered a UI/UX consistency enhancement by implementing a TitleCasePipe and wiring it into DatasetTableComponent and DatasetsModule, so dataset table headers render in title case by default. A focused bug fix (commit 383c2968a9808bebf9cfb419068a3676b3bde08b) ensures header text remains title-cased across views. Business impact: improved readability, consistency, and alignment with the design system, reducing user cognitive load when browsing datasets. Technologies involved include TypeScript and Angular (pipes, component/module wiring).
