PowerBed Platform is a three-phase sleep optimization SaaS architecture combining Next.js frontend, NestJS backend, Supabase PostgreSQL, and pgvector embeddings. Phase 1 establishes user authentication, product configuration, and payment via Stripe; Phase 2 adds IoT sensor data ingestion, sleep pattern vectorization, and ETL-driven analytics; Phase 3 layers AI model training, LLM endpoints, and RAG pipelines to deliver personalized sleep recommendations. This phased approach lets teams validate core product-market fit before investing in ML infrastructure, reducing upfront complexity and cost.
