+# Salesforce Development
+
+## Patterns
+
+### Lightning Web Component with Wire Service
+
+Use @wire decorator for reactive data binding with Lightning Data Service
+or Apex methods. @wire fits LWC's reactive architecture and enables
+Salesforce performance optimizations.
+
+
+### Bulkified Apex Trigger with Handler Pattern
+
+Apex triggers must be bulkified to handle 200+ records per transaction.
+Use handler pattern for separation of concerns, testability, and
+recursion prevention.
+
+
+### Queueable Apex for Async Processing
+
+Use Queueable Apex for async processing with support for non-primitive
+types, monitoring via AsyncApexJob, and job chaining. Limit: 50 jobs
+per transaction, 1 child job when chaining.
+
+
+## Anti-Patterns
+
+### ❌ SOQL Inside Loops
+
+### ❌ DML Inside Loops
+
+### ❌ Hardcoding IDs
+
+## ⚠️ Sharp Edges
