Hey! I'm Nathanael Barbey
I Turn Data Problems Into Reliable, Scalable Systems
I went from IT infrastructure to web development at an agency, giving me the perspective to see from the server to the screen. Now I build backends, APIs and data systems.
My GithubA Bit About Me(& My Code)
What I enjoy most is starting from nothing — a blank slate, an unsolved problem — and working through the possibilities. Which approach fits? What are the real-world constraints? What will this look like in six months? I like the headaches that come with hard problems, because the moment it finally clicks makes it all worth it.
When I'm not coding, you'll find me on a racetrack — either behind a sim wheel or at a track day.
