IT systems administrator. I automate infrastructure and build Claude skills, plugins & AI agents — all open source.
By day I keep the Microsoft cloud stack at journaway, a travel operator — Microsoft 365, Azure, identity, and endpoint security — secure, governed, and running. By night I build open-source MCP servers and agent tooling.
