## About

I architect enterprise GenAI systems, the kind that have to be reliable, evaluable, and affordable in production, not just impressive in a demo\. Over 11\+ years I’ve grown from full\-stack \.NET engineering into AI architecture, and I now design agentic LLM platforms end to end across AWS and Azure\. Right now I lead a multi\-tenant GenAI quoting platform on AWS Bedrock: customers forward packaging specs by email, LLMs extract the details, and the platform auto\-generates their quote — built with Bedrock agents, LangChain orchestration, a self\-improving correction\-memory layer, full IaC/CI\-CD, and LangSmith\-based evaluation and tracing\. Before this I built enterprise AI agents at BlackLine — an autonomous coding agent that takes a Jira ticket to PR and code review, plus email\-sentiment and customer\-outreach agents — and GenAI features for Epicor’s Prism cognitive\-ERP platform on Azure OpenAI\. A theme in my work is making agents efficient at scale\. One example: replacing full\-codebase context reads with a semantic code\-retrieval layer and incremental re\-indexing, cutting token cost per task by \~60%\. What I care about: agentic design, LLM evaluation, retrieval architecture, multi\-tenant isolation, and cost optimization — the engineering that decides whether AI actually ships\. I also mentor engineers on these patterns\. Open to Lead / Principal / Architect roles in AI/GenAI\. Let’s talk if you’re building agentic systems at scale\.
