about me ↓

I'm a senior full-stack software engineer with 13+ years shipping production web, mobile, and cloud applications. My core stack: C# / .NET (ASP.NET Core, Web API, MVC), Angular, Node.js, and MS SQL Server — deployed on Azure with end-to-end CI/CD.

I've architected secure, scalable systems for government (Nevada NCCIS, Nebraska Crime Commission) and healthcare (Mayo Clinic) clients, and I publish iOS apps on the side for the joy of shipping.

Lately I'm focused on AI/LLM integration — building RAG pipelines, agentic workflows, and conversational AI features with the OpenAI and Anthropic (Claude) APIs into real, shipped products. I also run local LLMs (Llama, DeepSeek) on Raspberry Pi for offline experiments.

📍 Rochester, MN

What I build

Three flavors of work I take on, in order of how loud I get about them at parties.

🧠

AI / LLM Systems

RAG pipelines, agentic workflows, and conversational AI on OpenAI, Claude, and Azure OpenAI — with safety guardrails and citation enforcement.

☁️

Cloud Architecture

Secure, scalable platforms on Azure (AD, Functions, Key Vault, Search), AWS, and Firebase — end-to-end CI/CD on Azure DevOps.

📱

Mobile Apps

Native iOS in Swift / SwiftUI / SwiftData and cross-platform with Expo / React Native — App Store + Google Play.
