🚀 Performance Engineering

This core engine is built for extreme efficiency and real-time reliability.

⚡ Aggressive Caching Strategy

Using Laravel Cache-Aside, we minimize database hits for frequently accessed data:

• Global Settings: Cached for 1 hour, auto-invalidated on update.
• Sales Intelligence: High-intensity analytics cached for 5 minutes.
• Notification Counts: Real-time unread counts cached for 60 seconds per user.

📊 SQL Intelligence

We moved heavy computations from PHP memory to the SQL Database Layer:

• Aggregated Queries: Using DB::raw for instant SUM/COUNT/GROUP BY across multi-vendor data.
• Optimized Indexing: Custom indexing on created_at and site_id ensures range queries execute in milliseconds.
