Binariks implemented a scalable, AI-powered pipeline that transforms document ingestion into structured, explainable, and auditable risk insights – meeting strict security and compliance requirements set by a global commercial insurer.
The architecture was shaped by key drivers such as high document complexity, the need for transparent AI decisions, and enterprise constraints, including encryption policies, Azure-only deployments, and fast MVP timelines.
Key Drivers and Constraints Addressed
- Data complexity: Required structured extraction from a high volume of unstructured claim and risk documents
- Auditability & compliance: Needed citation-backed outputs for regulatory traceability and internal audits
- Enterprise constraints:
- Azure-mandated cloud usage
- In-transit and at-rest encryption
- Only whitelisted services (e.g., Azure Blob, Key Vault) permitted
- No external LLM hosting allowed
- Time-to-value: A fast MVP delivery with scalable infrastructure was required
Key Architecture & Implementation Components
1. Document ingestion & OCR layer
- Converted scanned and digital claim documents into machine-readable text using Azure OCR
- Served as the foundation for downstream processing
- Implemented as a Dockerized FastAPI microservice with integration to Azure Blob Storage
2. RAG-based insight generation
- Designed a Retrieval-Augmented Generation pipeline using LangChain and LangGraph
- Model responses were grounded in source documents, delivering traceable, citation-backed outputs
- Complied with audit expectations for high-stakes decision support
3. Prompt engineering with chain-of-thought (CoT)
- Developed advanced prompting logic to guide LLMs through multi-step insurance reasoning
- Improved the accuracy and interpretability of extracted risk factors and potential losses
4. Reflection agents
- Integrated to self-evaluate LLM outputs by running multiple reasoning paths and selecting the most consistent result
- Enhanced reliability while minimizing the need for manual review
5. Evaluation & observability layer
- Deployed LangSmith to trace model responses, evaluate output quality, and monitor chain performance
- Used both automated tests and user feedback from business analysts to fine-tune prompt strategies
6. Secure, scalable infrastructure
- Fully containerized and deployed in Azure, aligning with the client’s enterprise security and compliance policies
- Used Azure Key Vault for secret management and enforced encryption in-transit and at-rest
- Integrated CI/CD pipelines, with automated deployments and scheduled refresh logic
- Supported environment separation (test, QA, production) for controlled rollout
7. QA & testing framework
- Built an end-to-end test suite using Pytest and automation tools
- Covered all workflow elements including:
- OCR edge cases
- LLM fallbacks
- Failure handling
- Integration flow between services
