The Sports Alert Engine revolutionizes fan engagement through its natural language processing core built with Python/Flask and Flutter. Key features include:

Intelligent Rule Processing

  • Natural Language Interpreter: Converts phrases like “WHEN Lakers lead ≤3 in last 5 minutes” into game logic using regex patterns and safe eval() execution
  • Context-Aware Parsing: Recognizes 50+ sports-specific terms (lead, OT, quarter) through custom tokenization
  • Dynamic Variables: Supports team names, players, and game metrics from ESPN API’s live data feed

Multi-Platform Delivery

  • Flutter Frontend: Cross-platform app (iOS/Android/Web) with team/player dropdowns and rule templates
  • Twilio Integration: SMS/email alerts with configurable delivery channels and timing preferences
  • React Dashboard: Web interface for non-technical users to manage subscriptions and alert history

Technical Highlights

  • Real-Time Engine: Processes 100+ concurrent games with <5s latency using WebSocket connections
  • State Management: Bloc pattern in Flutter for efficient UI updates during live game changes
  • Security: Rule sanitization layer prevents code injection in custom alert conditions
  • Analytics: Tracks alert accuracy and user engagement through Firebase integration

Performance Metrics

  • Handled 50+ concurrent users during NBA playoffs with 99.8% uptime
  • Reduced manual score checking time from 30min/game to instant notifications
  • Supported 15+ sports types through modular league-specific parsers

The Sports Alert Engine combines fan intuition with technical precision, transforming casual viewers into engaged analysts through accessible real-time intelligence.
