Project Context
Built ToFeel Useful.
Dream Veil is an AI-powered dream journaling platform built around contextual interpretation and semantic pattern recognition. Users record dreams, receive streaming psychoanalysis from user-selectable Gemini 3.5/2.5 Flash models with configurable thinking depth and optional multimodal image analysis, and discover thematic links across their history all while optional E2EE ensures the server never permanently stores plaintext narratives or interpretations.

Built a 6-phase production RAG pipeline: hybrid pgvector + BM25 retrieval, reciprocal rank fusion, cross-encoder reranking, grounding guards, and tiered chronological context assembly.
Streamed multimodal AI interpretations via Server-Sent Events with BYOK Gemini keys, Redis-backed RAG context caching, and intelligent API key rotation with tiered TTL exhaustion handling.
