acquia certification

I am planning to go for Drupal 8 Certification. Is there anyone in Tricity who is Drupal 8 certified, if yes which certification ? I need some suggestions related to Certified Developer and Front End Specialist.

Acquia Grand Master Developer Certification promo is about to end on December 31, 2015. I am attaching 2015 badges perfect for your profile use, if you'd pass the exams.

I have checked Aquia site here(https://www.acquia.com/customer-success/learning-services/acquia-certifi...) and found there are four types of certification.

Acquia Certified Developer Exam
Acquia Certified Developer-Back End Specialist Exam
Acquia Certified Developer-Front End Specialist Exam
Acquia Certified Drupal Site Builder Exam
But which certification Team Leam/Project Manager should do? Why this four certification? Who should do which certification? Can anyone explain. Do I need to all four certification?

I am at DrupalCon Austin, and on Wednesday, I noticed a room off to the side of the hubbub with a sign out front that read "Acquia Certification". I had heard about the program and had a certain amount of trepidation about it. Being a mostly homegrown industry, it can be difficult to have a feel for how sharp your skills are in comparison to others around you.
