In a fullstack project using React and NestJS, I worked on the
frontend by adding new pages, implementing record creation and
editing through modals, displaying data in a table with editing
functionality, and integrating APIs. On the backend, I modified
existing APIs and fixed issues related to data parsing.

Additionally, I developed a task management project on the
frontend, implementing responsive design and drag-and-drop
(DND) functionality for task organization. I also worked on
generating and displaying report charts for better data
visualization.
