About

I'm Jeff Widmer. I run TownBackyard Software, a Microsoft-stack consulting practice. I've been shipping .NET / Azure / Cosmos DB / ASP.NET work for 25+ years and I'm currently leaning into helping engineering teams adopt agentic-development tools (Claude Code, Copilot, MCP, Azure AI Foundry) in real codebases — usually .NET ones with constraints that JS/Python-flavored AI-dev advice doesn't account for.

This site is the learn-in-public side of that work — evidence over framework, deliberately unpolished. Posts when something synthesizes; notes more often.

Looking for consulting? Reach out via TownBackyard.

Disambiguation: I'm the engineer Jeff Widmer. There's also an author Jeff Widmer who lives nearby and owns jeffwidmer.com — different person. If you reached this page looking for the author, try DuckDuckGo with "Jeff Widmer" plus a topic that's not .NET, Azure, or Cosmos DB.
