An epinephrine auto-injector thin enough to live in your phone case — built for the 56% of people prescribed an EpiPen who don't carry one. The problem was never the drug. It's that the standard injector is bulky and easy to leave behind, so it fails in the pocket that stayed home rather than in the emergency room.

I lead mechanism design, customer discovery and the regulatory groundwork. The whole design is shaped by one constraint above all others: it has to clear the 510(k) substantial-equivalence pathway.
