Second Brain to Personal OS: A Live Demo of Agentic Cloud Engineering

Building a Second Brain That Actually Thinks: AI Agents + Knowledge Graphs for Cloud Engineers

What happens when you connect AI agents to a structured knowledge base with vector search, graph relationships, and async capture pipelines? You get agents that know your architecture, remember your decisions, and take action with context. Live demo of a system built on GitHub Copilot, MCP servers, and an Obsidian vault — managing sprint work, querying AWS, drafting architecture docs, and processing an inbox of ideas into actionable projects. This isn't prompt engineering. This is a personal engineering OS. 200-level, all live demo.
