# the idea
Customers in a sensitive category want private, knowledgeable guidance — not a search box. Aura answers like an expert and knows the catalogue.
# what I built
- Store with Stripe and PayU checkout, payment recovery, SMS and email notifications and a rich-text CMS.
- Admin dashboard with TOTP 2FA, drag-and-drop merchandising, scheduled jobs and order management.
- Aura: Claude-based assistant with user memory, knowledge-base RAG, voice input/output and image understanding.
- Next-gen Aura: fine-tuned open-weights model on the hot path, Claude as teacher/judge, shadow comparison and DPO retraining.
# key decisions
- Teacher–student loop to cut inference cost without dropping answer quality.
- Embeddings in Postgres (pgvector) rather than a separate vector database.
