Challenge
Enterprise customers needed tenant-safe retrieval across unstructured documents: graph-aware search, governed tool access, and hardening for compliance products. A single shared index and ad-hoc prompts were not acceptable.
Approach
- Owned the modular ingestion and retrieval service end-to-end: MCP tool surface, knowledge-graph retrieval layered with vector and BM25-style search, tenant-scoped collections, and auth/environment hardening.
- Built onboarding playbook for new organizations and document corpora.
- Shipped first production customer onboarding for a compliance SaaS knowledge base: org-scoped collections, governed MCP access, and auth hardening on shared multi-tenant infrastructure.

Outcomes
- Production RAG with explicit tenant boundaries, not a demo index
- Compliance product KB live for multiple orgs on shared platform
- Reusable ingestion/retrieval patterns for subsequent enterprise onboardings
Context
Compliance SaaS provider (customer anonymized): knowledge base for regulated product documentation.
