Project description:
"Refactor & Optimize [login to view URL] App (BetterAuth, Stripe, Client-Heavy, Clean Code)

Project Overview:

I have a fully functional Next.js-based web app for practicing exam-style questions (timed tests, answer review, analytics, etc.). The app works, but:
• The codebase is messy (poor naming, structure, organization)
• It’s a bit slow and bloated
• Some logic is server-heavy and could be moved to the client to save hosting costs and improve responsiveness

I’m looking for a developer to refactor and optimize the app, implement BetterAuth for authentication, set up Stripe monthly subscriptions with a 7-day free trial, and ensure the app is as client-driven and cost-efficient as possible.

I’m also open to suggestions for smarter tech or architecture improvements if it helps performance, cost, or maintainability.

⸻

Current Tech Stack:
• Framework: [login to view URL] (App Router)
• UI: Tailwind CSS + shadcn/ui
• Database: PostgreSQL (hosted via NeonDB)
• Auth: To be upgraded to BetterAuth
• Payments: Stripe (Monthly + free trial)
• Hosting: Vercel (goal is to reduce server function usage)

⸻

What You’ll Do:
1. Code Refactor & Cleanup
• Improve naming (components, functions, hooks)
• Modularize large components and logic
• Create a clean, scalable file/folder structure
• Remove dead/duplicate code
2. Client-Heavy Refactor
• Migrate server-heavy logic to client-side wherever safe and feasible
• Prefer Client-Side Rendering (CSR)
3. Auth Implementation
• Integrate BetterAuth for login/signup/password reset
• Secure sessions and route protection
4. Stripe Integration
• Monthly subscription with 7-day free trial
• Billing state synced with NeonDB
• Access control based on subscription status
5. Performance Optimization
• Bundle splitting, lazy loading
• Improve Lighthouse scores
• Minimal layout shift, fast interaction
6. Open to Tech Suggestions
• If you know better tooling or architecture for any part (auth, db, UI, DX), I’m open to hearing it

⸻

Ideal Developer:
• Experienced with [login to view URL] (App Router) and modern frontend architecture
• Strong sense of code cleanliness, naming, modularity
• Familiar with BetterAuth or similar modern auth libraries
• Can design scalable client-heavy apps that feel fast and are cheap to host

⸻

Please share:
• Relevant [login to view URL] project links
• Experience with Stripe + auth systems
• Any suggested improvements to the current stack or architecture
• Estimated timeline + budget" (client-provided description)
