Denis Knaack

I build production-grade AI systems in .NET: multi-agent orchestration, MCP/A2A integrations, retrieval over large codebases, and LLM grounding. My focus is where many initiatives get stuck: moving AI from prototype to stable, maintainable production systems.

Behind that work are more than 25 years of professional software engineering and deep backend experience in C#/.NET – from the first API design to deployment. TypeScript, React, and modern frontends remain part of my product reach, but the sharp edge is clear: agentic systems for .NET and enterprise environments.

I work remotely, independently, and conceptually. You provide the goal and context; I deliver against the specification with low overhead, clear communication, and ownership from architecture to delivery.
