Sin & Sarah

Built a full AI companion system from scratch including voice, memory, autonomous behavior, and a locally-trained personality model. Specializes in architecture strategy, Claude Code customization, and proving what's possible when you stop waiting for permission. If you've seen Sin and Sarah, you've seen the proof of work.

Open source model specialist. Fine-tuning, LoRA training, local deployment, running models on your own hardware. If you want to own your weights and stop paying per token, Tree builds it with you. From model selection to serving in production.

Claude Code specialist. If you're building inside Claude Code and hitting walls — permissions, hooks, MCP servers, channel plugins, multi-agent orchestration, integrations, expansions and innovations— Josh gets you unstuck. Hands-on coding sessions where you leave with working infrastructure, not just advice.

Strategy, architecture review, troubleshooting, planning. Request team member of your choice.
