Relevant Coursework: Data Structures & Algorithms, Applied Data Science, Database Management (SQL), Statistical Analysis

• Built a Random Forest classification model to predict win-from-deficit ("comeback") outcomes using 150K+ professional esports match records and early-state features at a fixed timestamp.
• Cleaned and prepared large-scale match data; created a reproducible dataset with engineered features capturing resource/experience gaps, objective control, and engagement efficiency.
• Addressed class imbalance (~16%) by optimizing for F1-score, applying class_weight, and tuning hyperparameters using GridSearchCV (k-fold cross-validation).
• Improved F1-score by 347% over baseline Decision Tree model through feature engineering and model selection; communicated tradeoffs using precision/recall rather than accuracy.
• Validated statistical claims using permutation testing and evaluated fairness across regions to confirm no meaningful performance disparity across cohorts.

• Analyzed College Scorecard dataset (6,000+ institutions) to investigate relationship between low-income student enrollment (Pell Grant %) and STEM degree share at U.S. public colleges.
• Conducted correlation analysis revealing statistically significant negative relationship (r = -0.107, p = 0.009) between low-income enrollment and STEM degree share.
• Cleaned and aggregated multi-dimensional educational data, filtering to 595 bachelor's-granting institutions and creating composite STEM metrics from 7 CIP code categories.

• Led a 4-person team to design and launch a project website and deliver a "survival guide".
• Presented to 30 students and 2 professors.
• Owned project coordination (task delegation, timeline, final pitch) and communicated design decisions clearly to a mixed technical/non-technical audience.

• Coordinated volunteer operations across multiple large community events, supporting 200+ service hours while managing sign-ups, attendance tracking, and event logistics.
• Built and maintained Google Forms workflows for event registration; streamlined communication by organizing group chats and sending pre-event briefings to 100s of participants.
