@Evgeny Shvarov  / @Developer Community Admin - THANK YOU for the feature that allows you to display your professional certifications in your profile, as well as the check-mark on your profile pic .... love it!

Has any thought been given to the second idea of being able to see a list of people who publicly listed a specific certification?  That would make the experts more discoverable.
 

^SSADMIN is a TrakCare utility so you will need to look in the TrakCare documentation on that (and/or add the TrakCare tag to this question - not sure if that will send out new notifications to people who follow that Tag).  The Production page from the SMP is for the InterSystems IRIS Interoperability Productions for which I linked docs above.  I am guessing the "Interfacing" is a specific TrakCare feature which uses Productions and other pieces of InterSystems IRIS Interoperability beneath the covers.
