Description

Full-stack solution with React Native UX/UI, FastAPI micro-services, RAG pipeline design, model fine-tuning, and end-to-end security.

Solutions

- Modular multi-persona framework: users switch assistants with one tap; each persona has isolated context, embeddings, and memory.

- RAG-powered knowledge hubs: curated datasets (case law, tech white-papers, CBT scripts, entertainment trivia) indexed in vector stores; retrieval tuned with dynamic re-ranking.

- Scalable FastAPI backend: stateless workers behind AWS ALB; horizontal autoscaling handles 5× traffic spikes.

- Conversation security: AES-256 E2E encryption, rotating device keys, and zero-knowledge cloud storage.

- Observability & AB testing: OpenTelemetry traces, custom relevance scoring, feature flags for rapid persona roll-outs.

- Future-proof extensibility: new assistants plug in via YAML persona manifests and one-click CI/CD pipeline.
