Hi, I'm Dan

Full-stack engineer with 13+ years of experience, currently focused on applied AI, developer tools, and enterprise software. I build bespoke production AI systems and developer tooling — including Claude Code extensions.

What I'm Building

  • Developer tools and plugins — intelligent model routing, persistent knowledge, custom skills and agents (including Claude Code extensions)
  • Bespoke production AI systems with multi-model orchestration, evaluation frameworks, and cost optimization
  • Enterprise software solving real workflow problems at scale

Featured Projects

Project What It Does Stack
claude-router Intelligent model orchestration for Claude Code — routes queries to optimal Claude model based on complexity. 50-70% cost savings. Python
claude-knowledge Persistent project knowledge for Claude Code — captures patterns and architectural decisions across sessions Python
carg-eval Evaluation harness for AI systems — 30 test cases, 5-dimension hybrid scoring, adversarial testing Python
ai-orchestrator Multi-model LLM routing service with Claude-first architecture TypeScript
