Performance & Scalability

Current Capacity

• Concurrent Submissions: Up to 10-20 simultaneously
• Daily Volume: ~500-1000 submissions (depends on API quotas)
• File Size Limit: Up to 100MB per pitch deck
• Storage: Unlimited (within Google Drive quota)

Scaling Considerations

For High Volume (1000+ submissions/day):

• Upgrade to paid API tiers
• Use queue system for processing
• Add database for tracking
• Implement rate limiting

For Large Files (>100MB):

• Use direct file upload to Drive
• Skip PDF generation for large files
• Add file size validation
