Apart from being a software developer, I enjoy most of my time being outdoors camping or travelling to see new places.

When forced indoors, I follow a number of television shows (Silicon Valley, Modern Family and The Big Bang Theory are my favourites). Of course, I'm a huge fan of tennis and Dominic Thiem is my favourite at the momemnt. And also I'm a fan of cricket by birth
