I build LLM-integrated systems
that actually ship.

RAG pipelines, agentic assistants, and Claude & OpenAI API integrations — built on 25 years of production enterprise architecture and a physics brain.

About

I'm a physics-educated software engineer who builds LLM-integrated systems — retrieval-augmented pipelines, multi-agent assistants, and Claude/OpenAI API integrations — on top of two and a half decades architecting enterprise-scale software for Fortune 500 insurers and defense programs.

Most "AI integration" is a ChatGPT call bolted onto a form. I build the real thing: stateful, multi-agent systems with vector retrieval, tool/function calling, streaming, and error handling that holds up in production. The engineering judgment comes from 25 years of building systems that can't fall down — the AI is just the newest layer on a very deep stack.

I'll tell you what's possible and what isn't, up front. No sales pitch, no hand-waving — straight answers and code you can actually maintain.

What I build

01

LLM API Integration

Claude or OpenAI wired into your app or workflow — streaming, tool calling, retries, secure key handling. Done right, not fragile.

02

RAG & Chatbots

Assistants that answer from your data — vector retrieval over your docs, grounded and accurate, not hallucinating.

03

AI Agents & Automation

Multi-step agentic workflows with tool/MCP integration — systems that do work, not just chat.

04

Architecture & Backend

The plumbing AI runs on — Java, Python, Node, SQL/NoSQL, Docker, CI/CD, DevSecOps. 25 years of it.

05

Legacy Modernization

Aging enterprise systems dragged into the present — containerization, cloud migration, CI/CD, security remediation. I've done exactly this at scale.

06

AI Architecture & Review

Not sure how to add AI to your product — or whether what you built is sound? I'll architect the integration or audit what you've got. Senior judgment, no guesswork.

Selected work

Persistent-Memory AI Assistant

A multi-agent assistant built from scratch with a temporal knowledge graph (thousands of nodes), retrieval-augmented context injection, Claude API orchestration, and MCP tool-servers running as always-on background services. Stateful memory that persists and retrieves across sessions.

Claude-Integrated Discord Bot

A live production bot with Claude API integration handling real-time community interaction — conversational AI wired into a Node.js service.

Enterprise Modernization at Scale

Lead Architect over ~30 Group Life applications at a Fortune 500 insurer: Azure DevOps CI/CD pipelines, containerized delivery to OpenShift, a .NET Core rules engine replacing 1,000+ manual rules, and org-wide security remediation (Log4Shell, WebSphere migrations).
