A multi-AI video pipeline behind 10,000+ realtor walkthroughs. High concurrency, fault tolerance, AWS deployment.
Overview
An estate-video automation pipeline: a multi-AI system that automates viral video content generation through a sequence of stages (script generation, voice synthesis, scene creation, post-production), running in parallel inside a unified, scalable backend.
Architecture
- Worker-queue: each AI generation stage is an independent worker listening for events.
- Custom event-emitter system coordinates transitions between stages without blocking the pipeline.
- Concurrency built in: stages run in parallel across multiple workers to handle many simultaneous requests.
- Containerized services on AWS for horizontal scaling and zero-downtime deployment.
Reliability & security
- Robust auth on every API and pipeline endpoint.
- Adaptive rate limiting prevents abuse and ensures fair resource usage.
- Built-in retry logic and event-based recovery handle transient failures gracefully.
- Comprehensive unit + integration test suite validates concurrency, queue behavior, and event-driven transitions.
Stack
- RUNTIME: Node.js + TypeScript
- PATTERN: Worker-queue, event-driven
- DEPLOY: AWS (containerized)
- CI/CD: Automated test pipelines
