Andrew Fribush
I'm Andrew Fribush, a software and computer engineer. I like data, electronics, and history.
I have a strange record of showing up near invasions and natural disasters. I carve wood, stone, and gem. I brew, blend, cook, and bake. I build bench electronics and open-source projects. I replicate economic papers about AI automation and decode ancient scrolls for fun.
I live between San Francisco, Austin, and New York.
Tell me what you're obsessed with and I'll get obsessed too. Always open to interesting conversations.
