Interests
Apart from being a Software developer, I enjoy going to the gym and staying fit. Also I'm an avid traveller and love exploring new places, people and relishing authentic food from all around the world. In my past time, I also enjoy reading books.
When forced indoors, I follow a number of sci-fi and fantasy genre movies and television shows.
