System Design: Theory to Implementation
An in-depth course on system design covering fundamental concepts and practical implementation strategies.
2024
WorldQuant University
Applied Data Science Lab
From this learning process, I have completed eight projects. Each project consists of four self-paced lessons, followed by an assignment. I learned various machine learning algorithms (Linear Regression, Logistic Regression, KNN, Naive Bayes, K-means, Random Forest, Decision Tree, ARMA, GARCH), various statistical techniques (Chi-square, A/B Testing, Regression, etc.), and big data analysis techniques (t- SNE, PCA). I built custom Python classes to implement an ETL process and created an interactive data application following a three-tiered design pattern. From this training, I gained skills in API design, data science, data visualization (Plotly, Matplotlib, Seaborn), Machine Learning, MongoDB, SQL, SQLite, and statistics.
