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
