Hi,
I can create developer from portal with custom attributes but how i can create developer categories from developer portal as we create developer categories at apigee edge,either created developer is company or individual .
Use Drupal roles to create developer categories. I am not sure what do you mean "developer categories at apigee edge", I believe roles in Apigee Edge.
Company concept in portal is available only with monetization. Leverage roles in Drupal CMS to categorize developers in portal.
