About
Senior engineer. No middlemen.
I'm Peter — a freelance senior .NET, DevOps, and cloud engineer based in the Netherlands. I've been building production software for over a decade, working with teams ranging from two-person startups to enterprise engineering departments.
When you hire me, you work directly with me. I embed with your team, understand your architecture, and deliver senior-level output — not delegated to a junior with a pretty slide deck in front.
