I started my data science journey back in 2017. I did my first natural language processing project during my Master's program. Got the dataset from a Kaggle competition. The project was Determination of Toxic Comments and Analysis for the Minimization of Unintentional Model Bias. The primary goal of this project was to design a supervised and deep learning model that can perform binary classification in order to determine toxic and non-toxic comments from a social network. My course instructor was really happy with the outcome and gave me a LinkedIn recommendation.

In 2018, when I started my MS program I…
