## Checklists & Cheatsheets

### Backend Developer Checklist
A checklist to ensure your backend application is production-ready before deployment:

- [ ] Database migrations are versioned (use Goose/Migrate)
- [ ] Environment variables are managed properly (not hardcoded)
- [ ] Structured logging (use zap/logrus)
- [ ] Health check endpoint (`/health` or `/ready`)
- [ ] Graceful shutdown implemented
- [ ] Rate limiting on public endpoints
- [ ] Input validation on all endpoints
- [ ] Consistent error handling (don't expose stack traces to clients)
- [ ] Database connection pooling optimized
- [ ] Backup strategy for database

### PostgreSQL Performance Cheatsheet
Quick guide for PostgreSQL query optimization:

| Issue | Solution |
|-------|----------|
| Slow query | Use `EXPLAIN ANALYZE` to identify bottlenecks |
| Missing index | `CREATE INDEX CONCURRENTLY` to avoid locks |
| N+1 query | Use eager loading (`JOIN` or `IN` clause) |
| Connection exhaustion | Implement connection pooling (PgBouncer) |
| Table bloat | Run `VACUUM FULL` or `pg_repack` |
