Senior full-stack engineer (23+ yrs) building web apps, APIs, and AI solutions in .NET, React, Next.js, Go, and modern LLMs (GPT, Claude).
Senior full-stack software engineer with 23+ years of experience building enterprise-grade applications, REST APIs, and AI-powered solutions. I specialize in C# / .NET 8, ASP.NET Core, Go, and React / Next.js with TypeScript, plus secure API design (OAuth/JWT) and SQL Server performance optimization.
I've architected large-scale systems including AI speech-to-text pipelines, real-time monitoring with SignalR, and full-text search and intelligence platforms. I also build modern full-stack apps with Stripe payments, PostgreSQL, and LLM integrations (OpenAI, Anthropic Claude), plus custom AI agents and RAG document search.
What I deliver: clean, scalable, secure code, on time and on budget. Whether you need a bug fixed fast, an AI chatbot or agent built, an API developed, or a full web app, I bring deep experience and clear communication to every project.
