Mobile App Developer for Booking/Ecommerce Platform

Looking for a developer to build out a mobile booking/business management app. The design is already fully mocked up — you will be figuring out very little UX or styling, only when needed. Main focus is just building it accurately and well. Design quality matters a lot here, so attention to detail is a must. WILL BE WORKING ON: Core app navigation and screens built from provided design mockups Calendar/scheduling functionality with recurring rules and booking windows Payments: card on file, deposits, tipping, chargeback evidence Two-way SMS messaging with usage limits Built-in ecommerce storefront with shipping label purchasing Email marketing tools (campaigns, segmentation, automation) Preferred tech stack, but flexible: React Native Supabase Stripe Connect (direct charges) Telnyx (SMS) Resend (email) Vercel Shippo (shipping/labels) Github Next.js (admin panel) Must be comfortable integrating third-party APIs end-to-end (Stripe, SMS, email, shipping) -- not just wiring up a wrapper library. Careful, detail-oriented about UI -- able to match a design precisely rather than approximate it Good communicator, reliable with async updates Part-time, with some weeks closer to full-time depending on build sprints Pay: up to $15/hour, based on experience
