• Analyzed entertainment ticket sales data from Snowflake, performed customer segmentation, and created Python visualizations to identify high-value customer groups for strategic marketing decisions
• Automated ETL pipeline for Looker dashboards using MySQL and Python, monitoring over 15 models' performance metrics, such as mean absolute error and custom-defined metrics, to detect model drifts
• Developed a machine learning model using Random Forest to predict ticket sell-through; recommended pricing based on predicted sell-through and business rules, resulting in an approximate $100k increase in fall profits
• Conducted experiments using MySQL to query six feature sets from multiple databases and Python for feature engineering presale pricing models, resulting in a 2-5% increase in ticket sales
• Documented projects process; shared model performance metrics and business insights with cross-functional teams

Title: Faster Solver For Multiple Linear Systems Via Block Conjugate Gradient. Improved a fast iterative solver for multiple linear systems. Updated conjugate gradients method to preconditioned block conjugate gradients (PBCG) method. Implemented four algorithms in Python and tested the speed of PBCG under fluid flow contexts. Increased the speed to find.

Title: Trace Reconstruction: Recovering the Original Message with High Probability.Consider that there is a random binary sequence. Every time there will be a new trace when the original random binary string is transmitted through a “deleting channel,” which extirpates bits arbitrarily with a random probability. Hence, we want to use distinct subsequences.
