I'm currently a Senior Consultant at Saama building NLP products with some awesome people. I am also a Mentor at Springboard, helping future Machine learning engineers and Data scientists in the weekends.

When I'm not in front of a computer screen, I'm probably playing badminton, photographing, or reading a book.
