As a SharePoint guy for around 10 years, I have been worked on all roles, SharePoint UI designer, Developer and Administrator. So I say I am an expert in SharePoint Technologies. And I also worked on different JS and CSS Frameworks like React, Angular JS, Knockout JS & jQuery and Bootstrap, Material Design & Office UI Fabric respectively. If you selected me I'll be suitable to work on any customization in SharePoint. To know more about me, please visit http://www.ktskumar.com
