Master of Science in Information Systems Dakota State University May 2024 Bachelors of Science in Computer Science Malla Reddy College of Engineering and Technology July 2022 Projects

Visualizer (Data Visualization and Machine Learning Tool Development): Developed "Visualizer," a comprehensive data analysis application, as part of a final semester project, implemented features for generating plots, graphs, and predictive analytics from user-uploaded datasets, integrated machine learning algorithms including decision trees, logistic regression, and KNN for classification tasks. Created a user interface for dataset uploading, visualization generation, and ML model utilization. Incorporated functionality to produce exploratory data analysis (EDA) reports for non-technical users, utilized Python, Power BI, and Tableau to deliver actionable insights in real-world scenarios. Successfully completed the project within a challenging two-week timeframe. Virtual Paint Application using Computer Vision: Built a real-time virtual paint application using Python and OpenCV, leveraging webcam input for interactive drawing, applied color masking and contour detection algorithms to track a physical object (e.g., Rubik's cube) as a virtual paintbrush, utilized computer vision techniques for object tracking, enabling smooth and accurate drawing on a digital canvas, integrated real-time image processing and rendering capabilities to create a responsive user experience. Demonstrated proficiency in video tracking, contour detection, and OpenCV's image processing libraries, successfully combined theoretical knowledge of computer vision algorithms with practical Python programming skills. Created an innovative interface bridging physical object manipulation with digital art creation. Certifications
