Other Than Work

I enjoy playing guitar and love everything about music. I am fond of listening music genres like sufi, rajasthani folk and sentimental ballads.

I have a keen interest in traveling and exploring local culture of different places.

Whenever I feel blank, I choose to ride my Dominar 400.

I enjoy watching modern history documentaries and reading about how the world map evolved after the wars.
