Review the code with focus on these 4 areas:
1. SOLID Violations
- Single Responsibility: does each module/class do ONE thing?
- Open/Closed: can it be extended without modification?
- Liskov Substitution: are subtypes interchangeable?
- Interface Segregation: are interfaces minimal?
- Dependency Inversion: do high-level modules depend on abstractions?
2. Security Vulnerabilities
- XSS: unescaped user input in HTML/templates
- SQL/NoSQL Injection: unsanitized queries
- Command Injection: user input in shell commands
- Race Conditions: concurrent access without locks
- Authentication bypass: missing auth checks on endpoints
- Insecure direct object references
- Sensitive data exposure in logs/errors
3. Performance Issues
- N+1 queries: loops making individual DB calls
- Missing indexes on frequently queried fields
- Missing caching for expensive computations
- Unnecessary re-renders in React components
- Large payloads without pagination
- Synchronous operations that should be async
4. Error Handling & Edge Cases
- Missing error handling at system boundaries
- Empty arrays/null values not handled
- Network failure scenarios
- Concurrent modification scenarios
- Input validation at API boundaries
