Permission-Aware RAG with Automated Planted Breach Tests
Key Architectural Innovations
- Query-time pre-ranking permission resolution against caller Entra ID OAuth scopes and security groups
- Automated conversion of Word, Excel, PowerPoint, and PDF into Markdown with YAML metadata headers
- 5-tier classification scheme (Public, Internal, Client Confidential, Restricted, Regulated) with human review for edge cases
- Automated quality gate with planted test breaches permanently blocking indexing upon any permission violation
- Plain-English operational runbook allowing non-technical practice managers to operate the pipeline without DevOps

Verified Production Impact & Client Endorsements
Real feedback from engineering leaders, CTOs, and founders across 15+ years of production deployments.
“Vijay and the SHIVAM ITCS AI team didn't just execute the project - they elevated our entire platform. Their ability to architect complex multi-agent state machines, eliminate latency bottlenecks, enforce zero-hallucination guardrails, and create an intelligent multi-LLM orchestration layer was extraordinary. The final delivery was resilient, battle-tested, and far beyond expectations. One of the strongest AI systems engineering teams in the industry.”
