Hello Mahesh,
I have attended a Regional Meetup back in Q3 2020 and it was also raised there.
As you can see we currently have the Architecture Specialization available, I believe we are still lacking 2 more specialization exams to be able to attain the Professional Reactive Web Developer Title/Badge. If I am correct, based on the previous meetup I have attended, we are still expecting for the Advance Reactive Development Specialization and Security Specialization Exams.
Please see a screenshot of the multiple paths below, containing info regarding both Professional Reactive Web Developer and Professional Mobile Developer.


Regards.
