I've been working with Microsoft Dynamics CRM since version 3.0 (both Online and On-Premise for CRM 2011 and 2013).
My experience included
1) Installation and configuration CRM.
2) Custom/Customize entities, attributes, forms, views.
3) web resources (html, javascript) integration.
4) Plugin and Workflow (custom workflow as well) development
5) Outlook Client integration.
6) ADFS/IFS Configuration
I am sure with my experience, I can help you in solving your CRM issues.
Sincerely yours,
John
