Leading a multi-tenant GenAI quoting platform on AWS Bedrock: customers forward corrugated-packaging specs by email, LLMs extract the details, and the platform auto-generates their quote. • Architected the end-to-end platform on Bedrock (Claude Haiku/Sonnet/Gemma),Lambda, S3, DynamoDB, API Gateway with tenant isolation. • Designed a self-improving correction-memory system that turns corrections into reusable inference rules, cutting recurring errors on degraded/scanned documents. • Consolidated RCA, Q&A, DB-query and content-lookup into a single Bedrock agent with Lambda action groups over pgvector. • Orchestrated agent workflows with LangChain; LangSmith tracing + evals; full IaC/CI-CD (Terraform + GitHub Actions). • Cut per-task token cost ~60% via a semantic code-retrieval layer with incremental re-indexing.

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.
