Worked on the care_fe repository to enhance validation and error handling within the bed-stay workflows and location time configuration features. Focused on improving user experience and data integrity by ensuring that validation errors are clearly displayed and that invalid date configurations are prevented. Applied robust error handling techniques to batch requests, reducing the likelihood of silent failures and providing clearer feedback to users. Leveraged React and TypeScript to implement these changes, emphasizing frontend development and UI/UX best practices. All updates were carefully linked to relevant issues and commits, supporting traceability and facilitating faster code reviews and audit processes.
