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
