Production AI Blueprints & Case Studies

Sample architectures engineered and deployed across enterprise workloads.

Enterprise Retrieval

Zero-Data-Leakage Multimodal RAG

Architected a sub-100ms enterprise knowledge retrieval engine using BigQuery Vector Search and Vertex AI Embeddings. Protected by VPC Service Controls with private IP endpoints, ensuring client data never leaves the security perimeter.

BigQuery Vector Vertex AI Cloud Run VPC-SC
Multi-Agent Systems

ADK Multi-Agent Orchestration

Engineered autonomous multi-agent pipelines leveraging Google's Agent Development Kit (ADK) and Vertex AI Agent Engine. Implemented A2A communication, stateful Memory Bank, and deterministic function-calling tools.

Google ADK Agent Engine A2A Protocol Firestore
FinOps & Governance

Cloud Monitoring Kill Switches

Designed automated budget enforcement architecture with Cloud Monitoring alerting, Pub/Sub, and Cloud Run kill switches. Cut unallocated cluster spend and token waste by 62% across high-concurrency LLM services.

Cloud Monitoring Pub/Sub Cloud Run CUD Optimization
High-Throughput Serving

GKE Inference on Cloud TPUs & vLLM

Built high-throughput open-weight model serving (Gemma 2/3, Llama) using vLLM on GKE Autopilot with Kueue priority queueing and Ray on Cloud TPUs, delivering 3.4x token throughput per dollar.
