I design, build and operate technology businesses.
I'm Ethan, an engineer and founder working across software, infrastructure and the businesses that run on them. I build systems I understand end to end, then turn them into products and companies people can rely on.
The common thread behind the work.
I've always been drawn to the whole system rather than a single layer of it. I like understanding how the network, the server, the software and the business model fit together, and I've found the most durable products come from people who can see all of them at once.
Most of what I build starts as infrastructure I wanted to exist. A homelab becomes a discipline for reliability. A school's admin problem becomes a platform. An IT headache becomes a managed service. I build the technical foundation first, operate it in the real world, and only then shape it into something other people can depend on.
My long-term goal is simple: own the infrastructure, understand it deeply, and run businesses that stay useful for a very long time. Engineering-first, calm, and built to last, not to impress.
