AI Architecture for Existing Systems

Bridging legacy enterprise infrastructure with modern foundation models, vector retrieval pipelines, and verifiable zero-trust governance.

AI Architecture, Microservices & Zero-Trust Integration Topology
🏢

Legacy Systems Integration

Connecting LLMs and vector databases with SQL databases, mainframe queues, ERPs, and internal REST APIs without compromising data integrity or existing business logic.

🔒

Zero-Trust AI Gateways & PII Sanitization

Implementing hardware-attested, on-premise proxy filters that sanitize PII, block prompt injection attacks, and enforce strict role-based access control before payloads hit LLM providers.

Hybrid Retrieval & Vector Topologies

Architecting scalable RAG systems combining sparse BM25 keyword search with dense vector embeddings (pgvector, Qdrant, Pinecone) and cross-encoder re-ranking pipelines.

📉

Semantic Caching & Token Optimization

Drastically reducing inference cost and API latency by routing similar prompts through Redis vector caching, local Ollama/vLLM fallbacks, and intelligent prompt compressions.

🔌

Microservices & API Gateway Governance

Exposing AI capabilities as secure REST/gRPC microservices with rate limiting, load balancing, model failover routing, and complete Prometheus telemetry.
