What I’m building
Two products that show how I run AI as the team.
Kronos Agent OS: an operational layer for AI agents, open source
KAOS — a self-hosted Python runtime for long-running AI agents with five-layer memory, multi-agent coordination, built-in automations, and defense-in-depth security. An open source alternative to Hermes Agent and OpenClaw.
JourneyBay 2.0: An AI Travel Engine That Holds the Entire Trip in One Itinerary
JourneyBay 2.0 is live - an AI Travel Engine that edits your trip instead of just answering questions. A trip from one prompt, booking import from PDFs and photos, visa context from official sources, bring your own LLM key, and MCP access for Claude Desktop, Codex, and Cursor.
