Full-Stack App Error Debugging and Rectification

Hi Freelancers

I have a full-stack Entertainment Web App already built using:

Frontend: React.js, Tailwind CSS, Redux Toolkit

Backend: Node.js, Express.js

Database: MongoDB

API: TMDB API for movies and series

However, the app is not functioning correctly on localhost. The frontend or backend might be facing bugs, build errors, or API integration issues. I need a skilled full-stack developer to:

Analyze the existing code (Frontend + Backend)

Detect what’s preventing the app from running properly

Fix the issues (routing, API, UI, Redux, MongoDB connection, etc.)

Test all features for smooth functionality

Pages and Features:
Home Page: Trending & recent movies/TV series grid
Movies Page: Movie cards with detail view
TV Series Page: Show cards with detail view
Bookmarks Page: Save/remove favorites
Sign Up & Login: Authentication flow (with optional profile image upload)
Search Functionality: Find movie/show by keyword

Assets I’ll Provide:
Complete source code (frontend + backend) via Github
Figma Designs (entertainment-web-app.zip)

Tools & Tech Used:
React.js, Redux Toolkit
Tailwind CSS
Node.js, Express.js
MongoDB
TMDB API

Expected Deliverables:
Fully functional app (local setup + deployment-ready)
Code cleanup if necessary
Error-free build and run
Clear instructions on how to run locally (updated README)

Ideal Freelancer:
Strong experience in MERN stack projects
Debugging and troubleshooting expert
Knows how to work with third-party APIs like TMDB
Can complete this quickly and cleanly
