Web application project

I need a skilled developer to continue work on an existing web app development. The project is built using Angular 8 framework with data connected to MySQL via API written on Python. The work is only on the Angular side, and nothing needs to be done with respect to the MySQL and API. However, both are required in order to debug the application to see the coding result. The requirement is quite straightforward for a well experienced developer hence I expect it to be completed in no more than a few hours. This excludes time taken to download the source code from my Gitlab and setting up MySQL database. Refer to the attached video in zip file for a clear understanding of the requirements. I need to incorporate reactive form control validation for input text box under VALUE heading within the “Subject Mapping” tab. The input shall be validated for numeric only (i.e., integer). There shall be an error message box (use ngx-bootstrap/modal) appear upon clicking “Save All” button if the validation failed. The message box shall display “Please enter correct number in VALUE box”. At this point, all data should NOT be inserted to the MySQL database tables. I attached with this job posting the MySQL dump file. Interested freelancers shall share their email and or Gitlab username for Freelancer to retrieve the project, execute the work, capture the result on video and submit it to me. I will award the job if the video shows the result I needed. Freelancer shall then commit and push the Angular project back to my Gitlab repo and payment will be made upon satisfactory execution of the code. Freelancer shall not remove original code but comment them instead. Any line added by Freelancer shall be marked with comment of Freelancer’s name. Freelancer shall not create new Angular component without informing me first.
