Constructed a low-cost, machine learning-based approach to detect life-threatening cardiac arrhythmias, evaluating its feasibility using both non-invasive signals from ECG data and simulations of internal cardiac activity.

Addressed class imbalance in the dataset using SMOTE and undersampling, then applied ensemble methods and tree based models, achieving 97% accuracy with 91% average recall rate in arrhythmia classification.

Predicted internal cardiac activation times at 75 myocardial locations using CNN (loss of 2 ms), and subsequently applied an LSTM (loss of 7 ms) to reconstruct the entire transmembrane potential curve.

Conducted market analysis of taxi industry by performing statistical analysis of market penetration, profitability, and demographic data, using hypothesis testing to identify profitable expansion opportunities and operational inefficiencies.

Operationalized a predictive model via Flask API locally, and containerized it with Docker for API deployment on GCP.

Built and evaluated an end-to-end project using bank marketing data to predict customer subscription outcomes, covering the full cycle from EDA to comparative ML analysis - achieved 91% accuracy and identified call duration and demographics as key drivers of subscription behavior.

Developed static websites for UCR student organizations using Tailwind CSS.

Collaborated in a team of 9 developers, attending weekly scrum meetings to align on project goals, troubleshoot design challenges, and enhance team coordination.

Completed a series of courses focused on neural networks, convolutional networks, and sequence models.

Completed a series of courses focused on data visualization, machine learning, and statistical analysis.

Completed a series of courses introduce the principles of data analysis, data cleaning, and data visualization.

Completed a series of courses in Python applications, covering topics from data handling and AI to creative tools and web development.
