I build consumer AI products. This is where I keep notes on better products, better decisions, and a more self-directed life.

This site is less a place for updates and more a place to preserve the standards I am trying to live and work by. I want to build a kind of philosophical firmness that does not stay as language alone, but eventually shows up in life, work, and products.

The questions I keep returning to tend to converge. Why do people come to love certain products? How can I keep making better decisions under uncertainty? What kind of systems make it easier to move in the direction I want without relying only on mood or willpower? And while holding these questions, how can I live with more agency?

I am less interested in finding perfect answers than in pushing imperfect choices into real life, then interpreting what happens. Writing is the trace of that interpretation. Product work is a way of applying it back to reality. Running, reflection, books, routines, startups, and AI are not separate interests as much as different angles on the same set of questions.

Much of this is still unresolved. So the writing here is closer to working notes than a manifesto. But if it accumulates long enough, I believe it can reveal what a person cared about, and by what standards he tried to shape his life.
