Hi there,
Greetings!
I understand you have requirement to configure / customize Dynamics 365 in that develop plugins, workflows, use REST API/OData. Also looking at customizing the Portal connected to Dynamics 365, and integration with third party apps.
My experience with Dynamics spans over 8 years and have implemented business solutions for verticals such as Real Estate, Healthcare, Staffing & recruiting, Legal firms... All these had plugins and workflows configured in addition to integrating with third party apps such as Xero, Fresh Desk, Marketing tools, and O365 apps that had Azure AD integration.
Happy to connect with you to discuss this project further.
Thanks,
Regards,
Rajesh Menon
