    GenAI knowledge platform at Sage

    2024 — 2026

    Multi-agent RAG with semantic caching across 7+ locales, ingesting 500k+ documents nightly into a hybrid OpenSearch vector index. A 15-metric LLM eval framework cut inference cost by 35% and pulled customer query response time from 2 hrs to 10 min.
