Designing an AI ad pipeline where a failed job never costs the customer a credit (Spring Boot)

Description and use

<p>AdPlatformForge turns one product photo into a short video ad or a social post design, in Arabic, French or Hassaniya. It is a multi-tenant SaaS: Spring Boot on the back end, Angular on the front, PostgreSQL, FFmpeg for video, and an LLM for the script.</p> <p>AI calls are slow, flaky and cost money. This post is about the four design choices that kept the system honest: the pipeline shape, the provider interfaces, the credit ledger and the safety checks.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto/https%3A%2F%2Fdev-to-uploads.s3.u
