EVA (RAG Assistant on AWS)

EVA is the RAG (Retrieval-Augmented Generation) assistant living in the bottom-right corner of the portfolio, answering questions about me. Full stack on AWS: embeds the question with Amazon Titan, retrieves relevant fragments of my CV, experience and projects from DynamoDB, and passes them to Claude Haiku 4.5 as context. Designed prioritizing cost control and honesty about retrieval limits (when it does not know, it says so instead of making things up).
