connector calendar Exo Platform 4.3

Hi,
Who can help me, guide me or charge me to develop a pair of connectors for the community of Bonita version 7.x

Connectors are to obtain, create, update and delete a calendar event in Exo Platform.

What not to do is the most important thing is the logical development of the connector.

Documentation Exo calendar API is here:
