I build things that run offline, sync in real time, or think for themselves.

Building small worlds since 2024.

Not just a job title

I'm a third-year Informatics and Computer Science student at Strathmore University, and most of what I make starts as a question I can't let go of: what if a room full of phones could act like one speaker, or a population of tiny philosophers could argue itself into new beliefs? This site is where those questions live alongside the more practical software I build for people.

Based in Nairobi, Kenya.

Off the clock

The things that shape how I think, even when they have nothing to do with code.

  • Games

    I'll admit to being unreasonably competitive about my own Sudoku solve times. Beyond that, I'm drawn to games with systems worth learning, not just reflexes.

  • Reading

    A mix of books and articles: fiction for the story, articles for whatever rabbit hole I'm in that week, usually something technical or philosophical.

  • Films

    I like films the same way I like Terrarium's agents: watching a system of ideas or people play itself out to an ending nobody planned.

  • Languages & culture

    Polyglot-in-progress. I'm collecting cultures, not just textbooks. The goal is understanding how people think, not just what they say.
