ABOUT THE AUTHOR

Hey, I am Raja Vikrant Sharma a student of BCA -2 at GGDSD College, Panjab University. I am fond of wildlife photography and recently got my two clicks published in the newspaper. Presently i am interning at a Website Development Company as a backend developer. I have developed an educational site named BCAHUB which is one year old and getting a traffic of 3500 page views per month. Now i am working for my YouTube channel Bcahub and TechBuzz . Less words , more actions...this is the dictum that I kept in my mind as I stepped into the campus of one of the most renowned college of my city, SD college. Like every novice I was too gripped by the anxiety on the first day of my college. The enthusiastic ambience of the college somehow proved a blessing for me.
