I write practical tutorials on Claude, AI-powered development, and modern .NET architecture. Building real things with real tools — and explaining how, from the inside.

// Background

I've been writing software professionally for over a decade — most of it in the .NET ecosystem, some in TypeScript, and lately a lot of time spent figuring out how AI fits into the loop without making the codebase worse.

This site is where I share what's working, what isn't, and the workflows I use day-to-day with Claude Code on real client projects. No hype, no theory — just shipped patterns and the friction points along the way.

// Now

What I'm working on

  • → Writing about MCP server patterns and the Claude Code Skills system.
  • → Shipping a redesign of this site (you're looking at the new direction).
  • → Open to consulting on AI-augmented .NET architecture engagements.
