about
Hi, I'm Juppy. I'm a software engineer — the kind who falls down rabbit holes, keeps half a dozen side projects on life support, and genuinely loves shipping things people use.
Over a decade of building for the web taught me the best work happens with people who care. So that's what I look for: brands and teams out to do something cool, who want someone to sweat the details alongside them.
