Job description

Build consumer apps from zero — the 0→1 seat, not the maintenance seat.

Alongside DansUGC we build consumer apps and market them with our own UGC engine. You'd be the engineer for that portfolio: idea to App Store, repeatedly, without a committee in between.

What you'll do

• Build consumer apps end to end — React Native / Expo or Swift, your call, defended.
• Ship to the App Store and Play Store: builds, review, releases, crash triage.
• Wire up the load-bearing boring parts — auth, payments (Stripe / RevenueCat), analytics, push.
• Instrument before the ads run, so growth isn't flying blind on launch day.
• Move fast. First version in weeks, not quarters.

What we're looking for

• You've shipped an app to a real store that real strangers used. Link it.
• Strong TypeScript, comfortable across the stack (we run Next.js 15 + Supabase + Cloudflare).
• You use AI tooling seriously, and it makes you faster without making you sloppy.
• You'd rather cut scope than miss a launch.
