Over a two-month period, contributed to both backend and frontend improvements across the netgrif/application-engine and netgrif/components repositories. Addressed API endpoint inconsistencies in the application engine by aligning controller mappings, ensuring public file previews were reliably accessible and simplifying future integrations. On the frontend, enhanced case view filtering in the components repository by supporting multiple filter types and improving filter state management, while also introducing defensive checks to prevent runtime errors. Implemented lazy loading for image previews to optimize performance. Work was delivered using Angular, TypeScript, and Java, with a focus on maintainability, reliability, and user experience improvements.
