Full-Stack Developer

Contract / Part-time → Full-time · Pangyo, South Korea

You'd be the first engineer working alongside the founder. Not maintaining a codebase someone else built — shaping the product from the ground up.

What you'd do

  • Build and ship core features across iOS and Android using React Native and Expo
  • Design and maintain backend systems with Supabase (PostgreSQL, Edge Functions, Auth)
  • Integrate health data sources — Apple HealthKit, Samsung Health SDK, and wearable APIs
  • Work directly with the founder on architecture decisions, not tickets handed down from a PM
  • Move fast. We ship weekly, not quarterly.

What we're looking for

  • Strong experience with React Native or Expo in production
  • Comfortable with backend work — Supabase, PostgreSQL, or similar
  • Can own features end-to-end: spec → build → ship → iterate
  • Bias toward shipping over perfecting
  • Bonus: experience with health data APIs (HealthKit, Google Health Connect) or AI/LLM integration

What we're not looking for

  • Someone who needs detailed specs to start building
  • Someone waiting for a team to form around them

Compensation

Competitive contract rate. Equity conversation possible for the right person as we grow.

We're not actively hiring for this role yet — we're building in public and want the right people to find us early.
