Info

Who runs the estate, in pictures and in words.

Lenn Okuro

Network engineer and infrastructure consultant between Zurich and Nairobi. I build systems the way networks are built: every concern gets one home, every boundary is a contract, and nothing trusts the layer beside it by default.

What I build towards: infrastructure a community can own. My master's thesis (design science research, Nairobi as the case) asks who owns the digital economy of a creative scene and what it takes to keep the value where it is made. The estate on the home page is the research artifact: identity, routing, storage, build and compute on owned hardware, deployed by pull, observed by a console that treats silence as a bug.

What that means for a business: one person who can design the network, gate the access, run the delivery pipeline, stand up a content plane and write all of it down so it can be handed over. Small means, large-platform practices, no lock-in.

I write logs the way I would explain a decision to a peer. If you run a team and want to own your delivery chain, that is the conversation I like most.
