Vikas Taank

My name is Vikas Taank and I hail from a small hilly town from India called Dehradun which is now the capital of the State of Uttarakhand. I was born and grew up in Dehradun and did my engineering from University of Rookie and passed out in the year of 2004. I studied the discipline of Pulp and paper technology which is not very popular in India. I always had a knack of creating content and story telling. During initial days of my career I worked with the companies like Infosys and then worked with Computer associates. I worked in the Credit Risk technology division of Royal bank of Scotland India. For the last past seven years I have been living in United States and now settled in Northern Virginia. I am married tom my awesome wife Rishu and have two boys named Advil and Ram. I have passion for story telling and using creative illustrations in my media and content. Any support on medium helps me to procure more resources in order to make my content better and also imaginative. I believe that illustrations helps us to memorize things bit through the concept of remembering though with the concept of connecting imaginations. Thanks a lot for Supporting me and also if you like my content please consider me supporting here.
