I don't just write code — I **define the architecture**. For over two decades I've been the person CTOs and lead developers call when a system is *failing under load*, a migration is at risk, or an AI integration needs to be done **right the first time**. With **21 years** of hands-on architecture experience, I specialize in **C#, .NET, Blazor, ASP.NET Core, SQL, Python**, and AI agents built with **Semantic Kernel, LangGraph, and custom tool-calling pipelines**. I design and deliver systems where performance, reliability, and intelligent automation aren't optional — they're the baseline. I've helped teams migrate from legacy .NET Framework to .NET 8, integrate AI into production pipelines, and recover systems failing under scale — without full rewrites. I've shipped AI to **production** — not to a Jupyter notebook. I'm the creator of **FreeAIVoice** ([freeaivoice.com](https://freeaivoice.com)) — a live AI voice platform with AI Voice Generation, Voice Cloning, and Speech-to-Text across **30+ languages** and a developer API. I know what it takes to build AI products that handle real users, real traffic, and real failure modes. --- **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 - **Legacy .NET Modernization** — refactoring strategy, migration paths, incremental upgrades - **Architecture Audits & Code Reviews** — identifying structural risks before they become production incidents - **Debugging Complex Systems** — when the stack trace doesn't tell the whole story
