My most recent coursework and projects I've completed during my education in Columbia has built my knowledge in several areas including machine learning, NLP, exploratory data analysis, computer systems, and statistics. I've worked as a Machine Learning Engineer after graduation and will start a Quantitative Analyst role soon
