Senior AI Engineer & Technical Instructor Building and teaching the next generation of production-grade AI systems.

Technical Lead and Senior AI Engineer with 20+ years of experience in large-scale enterprise systems. I specialize in Agentic AI, LLM platforms, and RAG, moving systems from fragile prototypes to secure, observable, and resilient production deployments. As an instructor, I bridge the gap between "code that works" and "architectural excellence"—empowering engineering teams to master reliable agent orchestration through evaluation-driven design and structural code boundaries.

Autonomous multi-agent system built using the Google Agent Development Kit (ADK) to replace manual repository exploration with instant architectural insights.

• The Architecture: Designed a "Root Agent" that intelligently delegates tasks to specialized sub-agents.
• Production Focus: Implemented context window management (memory compaction) and integration testing with deterministic tool responses to prevent agent drift.

A production-grade RAG pipeline providing source-grounded reflections on meditation and inner growth.

• The Stack: React, FastAPI, LlamaIndex, Pinecone, OpenAI GPT-4o-mini.
• Innovation: Utilizes Sentence Window Parsing to optimize vector database ingestion, prioritizing architectural boundaries and factual accuracy over unpredictable generation.

I teach through the lens of software architecture rather than just syntax.

• Python Decorators Finally Make Sense: Beyond basic syntax—how to use decorators as structural boundaries for resilient software. Features a self-healing @retry decorator designed to handle AI and network API instability.

• AI Orchestration: Google ADK, LangChain, LlamaIndex, Vertex AI, Multi-agent architectures.
• Production RAG: Advanced grounding, citations, and hallucination reduction.
• Cloud Infrastructure: AWS (Bedrock, Lambda, CDK, DynamoDB) & GCP (Vertex AI, Cloud Run).
• Leadership: IC+ style, owning end-to-end architecture while mentoring teams to deliver measurable value.
