Hiro Eernisse

Designer with a CS degree. I focus on product UI, the kind of work where decisions need to ship, not stall in review. I use Subframe and Claude to prototype and build quickly.

I'm drawn to early-stage teams where design is still being figured out. Open to full-time, contract, and freelance. Outside of work, I play drums in a heavy metal band.

Available for freelance projects and open to full-time roles at early-stage startups. If you need a designer who can move fast and ship, I'd love to talk.
