From need to production, with agents.
I've built AI into every step of my development workflow, from spec to production. Agents execute, test and prove. I step in where I add the most value: I frame the need and the business specification, I settle architecture choices, I challenge the existing code and I set the testing requirements. All on a hand-built Claude Code harness: shared plugins, conventions, quality gates, MCP server. And when existing tooling falls short, I build my own harnesses on the Claude Agent SDK.
