Senior React Native / Expo Engineer

Urgent React Native / Expo / TypeScript launch sprint for an existing production mobile app.

We are launching Orchy, an AI-first social/real-world planning app, publicly on 30 Aug 2026. Mobile binary needs to be release-ready around 22–23 Aug.

This is not a greenfield build. We already have an existing React Native + Expo + TypeScript app, TypeScript backend, Supabase/Postgres infrastructure, automated tests, iOS/Android release setup, and External TestFlight approval.

I need a strong senior engineer who can take ownership of launch-critical work including:

React Native / Expo / TypeScript implementation
AI/voice/chat product integration
onboarding, profile and verification UX
event creation, solo and group flows
maps / places / discovery
notifications, deep links and lifecycle handling
reservation and Razorpay/payment integration
physical iOS + Android debugging/testing
EAS/App Store/Play Store release preparation

Some functionality already exists, some needs hardening, and some requires meaningful implementation.

Requirements

Can start within 24 hours
Can work meaningfully through Aug 23, including weekend if needed
Has personally shipped production React Native/Expo apps
Real App Store and Google Play release experience
Comfortable taking over an existing codebase quickly
Strong debugging/API integration skills
Physical iPhone + Android access strongly preferred
AI-assisted development/agents are welcome if they improve delivery speed and quality

This will be a fixed-price, outcome-based sprint, not hourly billing.

In your proposal please include:

Your best fixed price for the sprint
Hours/days available through Aug 23
One production React Native/Expo app you personally shipped
Exactly what you owned on that app
Whether you personally handled App Store / Google Play release work
Whether you have physical iPhone + Android devices

I am screening over text first because of the deadline. Strong candidates will receive the detailed launch scope and can move quickly toward an offer.
