CRUD Page Development for Business Records

I'm seeking a proficient developer to create a web-based CRUD (Create, Retrieve, Update, Delete) page for my business. The functional page should comprehensively manage four different types of records: Employees, clients, timesheets, and timesheet entries. The ideal candidate should be proficient in: Creating, retrieving, updating, and deleting these specific record types Implementing a search functionality for timesheets and timesheet entries. Other records do not require this feature Developing a web-based interface for optimal accessibility and ease-of-use Must be skilled in Vaadin. You're the right person for the job if you're detail-oriented, experienced with CRUD operations, and a Web Development expert. Apply if your skill set aligns with my project requirements. Below are the implementation details. TimesheetEntry (long id, Timesheet timesheet, long clientId, long employeeId, LocalDateTime start, LocalDateTime end): The timesheet entry should be limited to the range set by the timesheet object it has a connection to and should extend from Base. Timesheet (long id, Employee employee, Client client, LocalDateTime start, LocalDateTime end, String notes, String clientSignature, String employeeSignature, String medicalCode, Decimal dollarsPerHour, List timesheetEntries, bool completed): Should extend base. Only the administrator can Browse, Edit, Add and Delete a timesheet. The read page is accessible to both the admin and the employee if they are logged in. The read page should have the functionality to add and remove timesheet entries. Either can add or delete timesheet entries but the entries can not overlap. If attempting to add an entry that overlaps with a preexisting entry, it should notify the user and prevent adding the data. On the read page, there should be a completed button that requires that both signature boxes are signed before the complete button can be enabled and pressed. Once the completed button is pressed and sent to the server, the complete flag should be flipped and the user should no longer be able to make any changes, although the admin still can. The browser page should have inputs to filter by start or end date, client name, or employee name. On the browse page, there should be a download document button that groups entries by ClientId, then by employeeId and medical code. Entries should be displayed from oldest to newest, with additional columns showing hours worked and payment amount. On the view page, their is a print button once the timesheet is completed and can not be changed that acts like the browse code but with a single timesheet as in input rather than many. Employee (long id, PersonalInformation personalInformation, String socialSecurityNumber): Should extend the Base object and use the base Service to follow system guidelines. When someone is added, they should automatically get an account created as just a user to the security account with a password generated for them as a UUID. Also, the add page is only accessible to administrators. When entering the SSN, it should hide all but the last 4 digits of the SSN, and the SSN should be stored securely. Only the admin can edit the employee information. On the view page, either the employee or the admin can see the page. It should have a show button that shows the full SSN if the owner of the account or the administrator is on the page, else it should just display the last 4 digits. There should be a view page that just lists simple information about all the employees' not-deleted data and their permissions. Only the admin should access this page. The page should have a delete button with confirmation that calls the services delete button which just sets the delete flag for the object. On the browsing mode, it should have a button to display all the timesheets with the employeeId equal to that employee id of the item the admin has clicked; additionally, it should be on the view page. Client (long id, PersonalInformation personalInformation, String socialSecurityNumber): Should extend the Base object and act basically like the employee object but only for clients. The client has no access to their pages; only the admin can Browse, Read, Edit, Add and Delete. Clean up and organize the data while fixing the spelling mistakes. Always aim to be more specific and verbose over losing any information. ------------------------------------------------------------------ ACCEPTANCE OF AGREEMENT.
