**Key Findings:**

2. Good separation of concerns with dedicated service classes
3. Medium issue: FCM initialization logic could cause problems in multi-tenant environments
4. Low issues: Missing template support, TODO placeholders for rate limiting/deduplication
5. Recommendations: Add integration tests, implement Redis rate limiting, add health checks
