I’m looking for an experienced React Native developer to help maintain and improve an existing mobile application that is currently live on both the Google Play Store and Apple App Store. The app uses Firebase as its backend, with some server-side functionality currently hosted on Bluehost. The project involves two specific tasks: 1. Font Update in Mobile App Change the current font used across the React Native app Ensure consistent styling across both iOS and Android Verify that the new font is properly bundled and renders correctly on all screens 2. Fix Scheduled API / Cron Job Currently, an API call is intended to run automatically on a weekly schedule. This is set up through a Bluehost server environment but is not functioning reliably. The goal is to implement a stable scheduled job (cron equivalent) that executes the API once per week without manual triggering Open to improved solutions (e.g., server cron, Firebase Functions scheduled triggers, or alternative reliable scheduling approaches) Tech Stack: React Native (iOS & Android) Firebase Bluehost (existing server-side setup) REST API integration What I’m Looking For: Strong experience with React Native styling and asset management Experience with backend scheduling (cron jobs, scheduled functions, or serverless alternatives) Ability to debug existing production apps without breaking live functionality Clean, reliable implementation rather than quick hacks If you’ve worked with Firebase scheduled functions or have experience moving cron jobs off traditional hosting into more reliable systems, that’s a strong plus. Please include examples of similar React Native or backend maintenance work you’ve done.

Next.js + Supabase Developer to Take SaaS App to Launch (Stripe Connect Required) I’m a solo founder finishing a club management SaaS (Next.js 16 App Router, TypeScript, Supabase, Stripe Connect, Vercel). The app is ~90% built and in pre-launch. I need someone to help close out the last features and bugs and get it shipped. You must have real, demonstrable experience with: - Next.js App Router — Server Components, Server Actions, the v15/16 model (not just client-side React) - Supabase — Postgres, RLS, migrations, auth - Stripe Connect — connected accounts, webhooks, idempotency (basic Stripe Checkout is not enough) Bonus if you have had an app you personally got accepted into the App Store, including how you handled payments. This is not part of this project but would be a phase 2.
