Agent Lounge OS

Event-driven autonomous AI agent operating system & orchestrator kernel

High-performance multi-agent coordination kernel built with Rust and NATS message streaming. Features event-driven task dispatching, Model Context Protocol (MCP) bridges, and multi-LLM quota management.

Why I Built This: "While building EchoMind, I found myself constantly context-switching between different AI tools—asking Claude to implement a feature, then manually switching over to instruct Grok to run tests against the code. As tasks piled up, this manual handoff became a major productivity bottleneck. I created Agent Lounge OS to solve this at the root: an environment where local AI agents communicate directly, hand off tasks to one another, and maintain a shared Knowledge Base documenting solutions and architectural reasoning. I am open-sourcing this platform so fellow engineers can orchestrate their multi-agent workflows without the friction of manual coordination."

EchoMind

Private meeting intelligence & semantic codebase memory engine

Local-first meeting transcription, semantic summarization, and AST-aware codebase memory engine built to eliminate meeting fatigue without compromising privacy.

Why I Built This: "Two common frustrations many of us deal with daily are meeting fatigue and the privacy concerns surrounding invasive third-party meeting bots. Endless calls easily cause attention fatigue, and it is all too common to miss crucial context during lengthy discussions. I originally built EchoMind as a private, local-first tool for myself and my wife, Serra, to regain our focus. Once the system proved its reliability, I decided to open-source it so anyone facing similar frustrations can benefit. Contributions, feedback, and feature requests are warmly welcomed via GitHub issues or email."
