Build webapp front end for existing backend, ability to help with in progress mobile app, paywall

This project is already underway. Your first responsibility will be understanding the existing architecture and extending it rather than rebuilding it. The primary responsibility, however, will be building the web version of the application. Experience with paywalls in both mobile and web is strongly preferred. I have a mobile app that is already in development with another developer. I'm looking to bring on a second developer for two reasons: Help accelerate development of the existing mobile app. Become familiar with the project so you can provide ongoing support after launch. Regarding the web version of the application: The web app will share the existing backend with the mobile app. Users must be able to sign into the same account on both web and mobile, with all authentication and data managed through the same backend. Current stack Backend: Supabase Mobile app: TypeScript + React Native Web stack I am looking for someone experienced with: TypeScript React Next.js Vercel Supabase GitHubExperience with Stripe/building a paywall also strongly preferred Development requirements Work from my existing GitHub repository. Follow Git best practices. Use clear branch naming conventions. Write clean, maintainable code. Document anything that another developer would need to understand in order to continue development if necessary. Experience building production React/Next.js applications that use Supabase is strongly preferred.
