I'm Sebastian, a product and technology generalist based in Germany. I've spent most of my career working on strategy, product development, and applied technology, sometimes with early-stage projects, sometimes with established teams. My interest in knowledge work, thinking tools, and AI brought me to Obsidian. From there I built Vault Operator, an autonomous AI layer for your vault. It runs on local or remote models, keeps your data where you want it, and the whole thing is open source.
