The platform uses a modular monolith architecture with strict component boundaries, database sharding through isolated pods, and extensive tooling investments including YJIT compiler and Sorbet type checker. The infrastructure handles 284 million requests per minute at peak, 66 million Kafka messages per second, and processes 216 million ML embeddings daily for semantic search, all while maintaining developer productivity through comprehensive CI/CD pipelines and observability tools. ## Full article daily.dev links to this article rather than hosting it.
