Sharepoint list item error

Hi, I'm Rohit. I posses 7 years of experience and my primary skills are in SharePoint development and related technologies. From my past experiences, I have handled SharePoint Development, SharePoint Migrations and SharePoint support and maintenance projects. I have worked on SharePoint 2007/2010/2013/2016/Online. With SharePoint Online and SharePoint apps development strategies, I also got accustomed to Microsoft Azure Development also. Currently I'm working as a SharePoint Consultant in a Multinational Organization where I'm responsible for handling all SharePoint related support and enhancements. I guarantee user satisfaction along with perfectness in work. Thanks, Rohit
