What you could do is redirect the user to that page after logging in with an anchor at the end of the url. For example:
www.mywebsitelandingpage.com#mike
Then to select one tag as active on page load, you can do something like that:
<a data-filter="dev-mike" class="<%= 'current' if current_user.name == "Mike" %>" href="#mike">Mike</a>
<a data-filter="dev-john" class="<%= 'current' if current_user.name == "John" %>" href="#john">John</a>
and then of course use some CSS to style the a tag with class="current"
