I define the architecture. For 21 years, I've been the person CTOs and lead developers call when systems fail under load, migrations are at risk or AI integration needs to work right the first time.
With expertise in .NET, Python, Blazor, ASP.NET Core, SQL and agentic AI architecture (LLMs, reasoning engines, Semantic Kernel, LangGraph, tool-calling agents), I design systems where performance, reliability, and intelligent automation aren't optional—they're the baseline.
I deliver AI in production, not prototypes. I’ve architected and deployed AI-powered systems across financial platforms, education and exam automation, and real estate market intelligence, including enterprise-grade solutions for organizations such as The New York Times, Project Management Institute (PMI), Walmart, Merit Wealth, Namfus and BlueberryCMS.

**Here's where I'm most useful to you:**
- **The AI Integration Trap** — You've been asked to add AI to your existing .NET system but don't know whether to use *Semantic Kernel*, raw OpenAI APIs, or a Python sidecar. I've made that decision dozens of times. I'll make it faster and safer for you.
- **The Blazor Bottleneck** — Your Blazor app is slow, state management is tangled, and you're unsure if you chose *Server or WASM* incorrectly. I can diagnose what went wrong and map a clean path forward — often in a single session.
- **The Legacy Modernization Cliff** — You have a 10-year-old .NET system that needs AI or modern tooling but wasn't designed for it. I specialize in *incremental refactoring paths* that don't require a full rewrite and don't break what's already working.
---
**What I Do Best:**
- **Software Architecture & System Design** — scalable, maintainable systems from greenfield to enterprise
- **AI Agent Development** — production-grade agents with Semantic Kernel, LangGraph & AutoGen — *not demos*
- **Blazor & ASP.NET Core** — Server, WASM, hybrid — full-cycle development and performance tuning
- **Python & AI Automation** — RAG pipelines, workflow automation, voice AI, LLM integrations, chatbots
- **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades
- **Architecture Audits** — identifying structural risk before it becomes a production incident, not after
- **Debugging Complex Systems** — when the stack trace doesn't tell the whole story
**If any of this sounds like your current situation — DM me. I respond to every message.**
