MongoDB Certified DBA

MongoDB University Offers Comprehensive Exams Worldwide

NEW YORK, NY- Nov 6, 2013 - I am very glad to announce that I have earned certification as a MongoDB Certified DBA, Associate Level

About a month ago, I was offered to try out MongoDB Certified DBA exam as part of a pilot project, invitations only. Before that, I successfully passed both M101 and M102P courses (well that was almost a year ago).  Invitations were sent to a selected group only, and only 150 first were given a chance to try that exam. It was thrilling to receive congratulating email in my inbox today, saying that I have successfully passed this quite difficult exam. Certificate number is 100-000-011 which indicates me being 11th in the world getting this (links to verify will be available little bit later).

According to The 451 Group's analysis of LinkedIn® member profiles, MongoDB is the most popular NoSQL database and now accounts for 49 percent of all mentions of NoSQL technologies. The formal certification will expand this reach and enhance the already thriving MongoDB online community.
I have been using MongoDB in production for about a year now. To keep things scalable, we have 3-node replica set (no sharding, yet) which has suffered no downtime since launch. Continuing being MongoDB NoSQL advocate in our company and mentoring, teaching and tutoring others will be my primary goal. We are already porting some of our products from MySQL Multi-AZ setup to MongoDB, and new apps will be built only on NoSQL, which allows us rapid growth and agile development.

Want to get certified? Here's what you need to know.
