Hey, I'm Peya. I'm a Business Systems & Financial Intelligence Engineer at Designed Realty, where I build the systems and data tools behind the business.

I got here through psychology. I graduated from the University of Washington Bothell with a degree in Psychology and worked as a behavior therapist. I've always been fascinated by the "why" behind human behavior, and I still bring that curiosity to every system I build. When I'm not working, I'm probably experimenting with new ideas, planning my next project, or relaxing with a cup of coffee.

    I build things that scratch my own itch: AI tools, data pipelines, servers, and automation. Mostly self-taught through Linux, open source, and breaking things until they work.

  18. Coffee

    One of those things I genuinely nerd out about. Not in a snobbish way, more like the same energy I bring to configuring a new Linux setup.

  19. V60 Pour Over

    daily driver

    Slow pour, watching the bloom, dialing in the grind. Clean, bright, and you can actually taste the origin.

  20. Aeropress

    most versatile

    Inverted method, different steep times, coarser grinds. Espresso-adjacent or a clean filter cup from the same device.

  21. Espresso

    high skill ceiling

    Working on consistent 1:2 ratio shots. The difference between a 25s and 30s pull is wild.

  22. French Press

    lazy Sunday energy

    Full immersion, thick body, zero fuss. Coarse grind, 4 minutes, done.

  23. Get in touch

    End of the line. Say hi.

    everything off the clock
