About

I'm an AI Architect and hands on AI & Data engineer. I design the architecture, and I write the code needed to prove it, improve it, and ship it.

1M+ engineers, architects, and AI practitioners follow my work across Linkedin, X and Instagram. I publish practitioner level architecture breakdowns, visual explainers, and practical frameworks covering agentic AI, evals, MCP, AI infrastructure, and governance. 250K+ builders read my newsletter.

16+ years building secure, production grade AI and data platforms inside complex regulated enterprises across financial services, healthcare, and insurance. Patent holder in AI and fintech. Selected as one of 11 technical creators for the Oracle Creator Lab.

What I work on:

→ Agentic and multi agent systems: orchestration, planning, memory, durable execution and state, tool use, failure recovery, human in the loop, and AgentOps

→ Evaluation and observability: eval harnesses, LLM as judge, tracing, regression testing, drift and hallucination measurement, and closing the gap between benchmark performance and production behavior

→ Agent identity and security: verifiable identities for agents, users, tools, and workloads, delegated authorization, least privilege, consent, provenance, prompt injection defense, and zero trust controls

→ AI governance: policy enforcement, permissions, human approvals, red teaming, model and data jurisdiction, explainability, auditability, and Responsible AI

→ Enterprise RAG and GraphRAG: hybrid search, context engineering, query rewriting, retrieval optimization, grounding, and evaluation

→ AI infrastructure: multi model routing, inference cost and latency optimization, vLLM, BentoML, Kubernetes, GPU workloads, AI gateways, and hybrid local and cloud execution

Built with Python, FastAPI, LangGraph, Google ADK, Microsoft Agent Framework, MCP, vector databases, Kafka, Spark, Docker, Kubernetes, MLflow, AWS Bedrock, Vertex AI, and Azure AI.

I treat identity, governance, permissions, provenance, and trust as infrastructure. They cannot be documentation added after deployment. Every AI system should deliver measurable value, manageable risk, operational resilience, and sustainable total cost of ownership.

The next frontier is trusted infrastructure for intelligent workflows. That is where I'm focused.
