Overview
An analytics engine that turns raw match logs into readable performance signals: efficiency by rotation, attack distribution by zone, serve pressure, and opponent tendencies.
02 /
The Problem
Match statistics are usually recorded but rarely interrogated. Coaches and players end up with totals instead of patterns, which makes it hard to prepare for a specific opponent.
03 /
The Solution
A Pandas pipeline that normalizes rally-level data, then a React dashboard that renders it as court heat maps, rotation efficiency, and per-opponent tendency profiles.
04 /
Architecture
Ingest → transform → serve. A pure-Python analysis core with a thin presentation layer keeps the statistics testable in isolation.
05 /
Technologies
Python, Pandas, NumPy, React, Chart.js.
06 /
Technical Decisions
Keeping the analysis layer framework-free meant the same code powers both notebook exploration and the web dashboard without duplication.
07 /
Challenges
Small-sample noise. Rates over few attempts are misleading, so the engine reports confidence context alongside every derived metric.
08 /
Security Considerations
Roster data is treated as private: no third-party analytics, local-first processing, and no personally identifying fields in exported datasets.
09 /
Results
Match preparation moved from raw box scores to zone-level tendency reads.

What I Learned
Data products live or die on how the number is framed, not on how the number is computed.
