    I deploy and manage AI assistants on all type of servers. I run my own multi-agent OpenClaw system in production daily, so when I set something up for you, it is the same approach I trust for my own infrastructure. My focus is taking a blank VPS or local setup and turning it into a fully working, secured, and documented AI assistant deployment — ready for production use. • OpenClaw installation, agent configuration, and channel integration (WhatsApp, Telegram, and others). • VPS/local setup, security hardening, and ongoing server administration. • Cost optimization to keep API expenses as low as possible. • Clean documentation and handoff so you can manage things independently. Based in Norway. I communicate clearly, deliver on time, and take ownership of my work. menos
