Ajeeth Ganapathinageswaran, a Solutions Architect at Cognizant Technology Solutions, discovered MongoDB through a friend's introduction to an upcoming meetup at the UN. He became interested in learning more about the database and began reading and playing with it after attending the schema design session conducted by Buzz Moschetti. Ajeeth pursued certification after completing the University training courses and found that hands-on practice was key to preparation. Since becoming certified, he has further explored MongoDB's applications in data engineering and analytics, inspiring him to learn more about NoSQL data stores and big data platforms. Ajeeth encourages others to pursue certification, sharing his experience and tips, and cherishes the community of like-minded people who have been inspired by his story.
