ELO Tracker App

Overview

Built a full-stack analytics app that converts friendly game results into a live ranking and performance-tracking system. The platform supports a private user base of close to 100 people, with player profiles, ELO movement, win/loss records, head-to-head comparisons, partner synergy, strength of schedule, and recent match history.

Outcome

• Implemented an ELO-based rating engine that updates player rankings as new match results are submitted.
• Designed React dashboards for player-level metrics including current ELO, peak ELO, win rate, streaks, total games, and ELO-over-time trends.
• Built analytics views for matchup context, including head-to-head records, best partners, nemeses, and strength-of-schedule comparisons.
• Connected the product to a PostgreSQL-backed database so rankings and match history update continuously for real users.
• Continuing to expand the product with additional game modes and broader analytics functionality.
