FAQ
Why does my AI SaaS need a Redis or Celery queue system?
AI APIs take 10–40 seconds to respond. Standard servers will timeout or freeze during this wait. A background queue (Redis/Celery) processes these heavy tasks asynchronously, keeping your web app lightning-fast.
Can you fix my broken Stripe payment flows or webhooks?
Yes. I audit payment sync issues, fix failed webhooks, and ensure user access tiers update instantly upon successful checkout, subscription renewal, or cancellation.
