About

The question I keep coming back to is “why was it built this way?”

Whether it's AI memory, market infrastructure, or developer tools, I enjoy figuring out why something works before building on top of it. Once you understand the architecture, most things stop being magic. Then the interesting problems become obvious.

That habit shaped my path. I started as a software engineer building scan and pay apps and supply chain systems. Then I spent three years in developer relations, first at Fetcch and then at SOON SVM, explaining systems to smart people every day. There's no faster way to find out which parts you don't actually understand.

Now I'm building Lads: an AI-powered private fitness companion for close friends. It helps small groups stay accountable, sync activities, and turn progress into useful coaching without making fitness a public feed.

Away from the keyboard: trails, and films I've already seen too many times.
