I build apps — and design the rest.

Used to make posters for bus stops. Now I make products for phones. Same obsession — the details you only notice when they're wrong.

The builds

Three live apps. Solo — designed, coded & shipped from one laptop.

001 in beta web × iOS × android

NOTTO

The list of things you'll never do.

Your to-do list will never be done. Ever. Notto is a list that actually ends — every item is a thing you've decided never to do again. Add it, strike it, slip it. A quiet iOS app for intentional refusal.

TRIPBOARD

Save the spot now. Find it when you land.

Share any spot from Instagram, TikTok or Maps and TripBoard reads the link, finds the exact venue and pins it — color-coded — to the right trip. From chaos to a map you actually use. Private end to end: it syncs through your iCloud, not someone's server.
