Bhavin Mistry • Senior Engineering Manager Melbourne, Australia

Architecting the systems that take enterprise AI to production.

I bridge business imperatives with modern AI engineering, Model Context Protocol (MCP) gateways, and hybrid retrieval platforms. My focus is taking Generative AI and autonomous agents from fragile prototypes to secure, governed production at Tier-1 banking scale.

System Design

Enterprise Architecture Blueprints.

Reference architectures and security topologies developed to bridge the gap between AI proofs-of-concept and scalable enterprise production.

Enterprise RAG Production Blueprint

Enterprise Hybrid RAG Architecture

A battle-tested production blueprint for enterprise search and knowledge retrieval combining dense semantic embeddings, sparse BM25 indexing, and cross-encoder reranking.

Core Problem: Pure vector search frequently misses exact keyword IDs, acronyms, and product codes, while suffering from vector drift and permission blindness across corporate data silos.
Agentic AI Production Blueprint

Agentic RAG Architecture

Multi-hop query decomposition, dynamic query reformulation, and autonomous citation critique for high-complexity enterprise research.

Core Problem: Traditional one-shot RAG fails when a user question requires aggregating information across disparate systems, comparing temporal periods, or reconciling conflicting data.
AI Platform Production Blueprint

Enterprise AI Gateway Architecture

A unified reverse-proxy platform layer enforcing security, multi-provider model routing, semantic caching, token quotas, and audit logging across all enterprise apps.

Core Problem: Uncontrolled proliferation of direct provider SDK keys, lack of central usage visibility, sudden cloud quota exhaustion, and unmonitored data egress.
AI Security Production Blueprint

Secure Enterprise AI Architecture

Defense-in-depth security framework protecting production AI systems from indirect prompt injection, data exfiltration, jailbreaks, and adversarial poisoning.

Core Problem: LLMs inherently blur the line between control logic (system instructions) and untrusted user input, opening severe vulnerabilities to indirect injection via external data.
