  1. Step 1Deploy RabbitMQ and Wire Up Producers and ConsumersRun RabbitMQ on Railway, expose the management UI, and connect producer and consumer services over private networking with Node.js and amqplib.
  2. Step 2Run an Embeddings Pipeline with an External API and pgvectorDeploy a batch worker on Railway that generates embeddings through an external API and stores them in Postgres with pgvector. Covers schema design, safe concurrent processing, and the psycopg2 vector adaptation gotcha.
  3. Step 3Deploy an LLM Gateway with LiteLLMDeploy LiteLLM Proxy on Railway as an LLM gateway for multiple providers. Covers model routing, cost tracking, API key management, caching with Redis, and private networking.
