About

Endlessly optimistic, with a firm belief in the power of hard work to conjure 'luck'. Waking up today looking to learning something new, so I can do my part leading this world into a brighter tomorrow. As a Data Scientist, my experiences have led me to believe that I have chosen well, as no domain shows more promise in changing tomorrow’s world than Data Science. I am a graduate student, pursuing my M.Sc. in Data Science at Columbia University, New York and I excel at translating skills picked up in classrooms into practical, scalable solutions of value to the industry. Through my journey as a graduate student, I have taken up extensive coursework in Data Science, Machine Learning and Reinforcement Learning. I have also interned at one of the world's largest reinsurance firms, and have experience as a graduate research assistant and Subject Matter Expert for Data Science. I believe I am now ready to put this experience to good use and would love to be part of an ecosystem where I can learn and contribute in a positive way utilizing the skills I posses and acquire.
