Selected Work
AthleteDesk
A purpose-built CRM for sports agencies — replacing disconnected spreadsheets with a unified platform for recruiting, roster management, brand deals, and team coordination.
TrackHub
Mobile app for tracking college track & field athletes, meets, and performances. Features leaderboards, athlete profiles, head-to-head comparisons, and meet results.
B2B SaaS Onboarding Experiment
A project management company tested a guided onboarding checklist across 2,000 new accounts. Overall activation improved, but the deeper story was in the segments: smaller teams benefited while enterprise-oriented accounts did not.
NYC Rideshare Operations: Analysis & Dashboard
An analysis of 62.4 million NYC trip records asking a simple question: where is rideshare supply lagging demand? The clearest signal showed up in residential Brooklyn, not Manhattan, and a live dashboard makes the pattern operational.
Drug Reviews NLP
Analyzed 215K patient reviews to identify underperforming medications and quantify $27M+ in revenue risk from drug non-adherence. Built an interactive Streamlit dashboard.
Olist Multi-Seller Analysis
Discovered that multi-seller orders drop customer satisfaction by 32% (4.18 → 2.86). Statistical analysis of 99K orders with ROI-backed recommendations.
E-Commerce Funnel Analysis
Analyzed 109.9M events from 5.3M users to identify conversion bottlenecks. Found 46.3% cart abandonment and weekend outperformance patterns.
About Me
I'm a graduate student in Data Science and Analytics with a strong interest in how data can be used to understand and improve real-world systems. I enjoy working through messy, unstructured data, figuring out what actually matters, and turning that into something clear and actionable.
I build practical solutions. Whether it's analyzing data, structuring databases, or creating systems that make information easier to work with, I focus on making things that are not only technically sound but also useful in real scenarios.
Alongside that, I spend a lot of time building things on my own: apps, tools, and small systems that start as ideas and turn into something real. It's how I explore problems, test ideas, and continue learning outside of the classroom.
