    Learning never stops....... Denison University a small liberal arts University in Ohio, United States was one of the first colleges to offer a Data Analytics curriculum. However, I was not satisfied with it as Data Science was something I wanted to be good at as it gives me the power to make and break systems. Hence, I decided to go abroad to Copenhagen for an intensive six months of Neural Networks and Deep Learning Course. After which, I found my niche in computer vision, and all my college and research projects revolve around that topic. I believe I am proficient in machine learning and computer vision. However, learning never stops, and I keep improving myself. The two domains that I am constantly teaching myself currently are NLP and Reinforcement Learning, which I can say that I am not great at now. In my free time, I create applications and websites. I am the founder and CEO of Seema Analytica, a flexible state-of-the-art data consultancy firm in India which I founded 2 months ago. Our goal is to help enterprises and institutions realize how much-unused data they are sitting on and help them utilize that data efficiently. We believe in levelling the playing field for all individuals and enterprises, be it big or small, by providing them with affordable data-oriented solutions to their specific problems.

    Currently a student, 1st year, studying in fields of data science and information technology. I aspire to acheive masterey for data science, and currenty am focusing on the very first step of data analysis - Data retreiving, Mining, and Visualization. Afterall, to make use of data and find answers to relevent questions, first thing to do it to have the data, more so, useful data, and then understand whatever knowledge it has to offer. As it stands proven, Humans can understand visuals about 3000x times faster as compared to textual representations. This is the role and potential of Data Visualization, quite underrated, but highly impactful. It being so crucial also calls for the best possible Visualizations of the most relevant information. That was a long essay, ---and all about what I do.
