About this gig
Is your existing website broken, unfinished, or showing unexpected errors?
I will diagnose and fix HTML, CSS, JavaScript, Firebase, Firestore, and responsive UI issues.
I can help with:
- JavaScript errors and broken features
- Buttons, forms, navigation, and popups
- HTML, CSS, and mobile layout problems
- Firebase Authentication and Firestore
- Security rules, queries, and indexes
- Login, registration, and user profiles
- User, creator, and admin roles
- Protected pages and approval workflows
- Cloudinary media uploads
- Music-player and media functionality
- Improvements to existing features
I recently completed a Fiverr client project for a music platform involving Firebase authentication, artist and admin roles, content approvals, Cloudinary uploads, artist profiles, music playback, video and news integration, and website bug fixes.
You will receive clear communication, careful debugging, testing, and an honest scope.
Please contact me before ordering. Send your technology, source-code status, errors or screenshots, expected result, and deadline.
Large features, redesigns, and unrelated issues require a custom offer.

FAQ
What information should I send before ordering?
Please send the website technology, current problem, screenshots or error messages, source-code availability, expected result, and deadline.
Can you work on an existing website?
Yes. This Gig is primarily for fixing and improving existing HTML, CSS, JavaScript, Firebase, and Firestore projects.
Can you build a complete website?
This Gig focuses on fixing existing websites and implementing defined features. A complete website requires an individual scope, price, and custom offer.
Can you integrate Firebase Authentication and Firestore?
Yes. I can help with email-and-password authentication, user profiles, Firestore collections, security rules, indexes, user roles, and protected pages.
Can you fix Firebase permission errors?
Yes. I can inspect Firestore queries, document structure, authentication state, security rules, and required indexes. The final solution depends on the project’s current configuration.
Can you add an admin dashboard?
I can add or improve defined admin functionality, including user roles, protected access, content lists, and approval workflows. Please contact me for a custom quote.
Can you integrate Cloudinary?
Yes. I can integrate Cloudinary into suitable existing JavaScript projects for image, audio, or other supported media uploads.
Do you provide hosting or paid services?
The package does not include hosting, domains, paid APIs, Firebase billing, Cloudinary plans, or other third-party charges. The client is responsible for third-party accounts and fees.
Will you need access to my accounts?
Usually I need the source code and relevant project configuration. Never send passwords in ordinary messages. Use secure invitation or team-access features when account access is necessary.
Do you provide unlimited revisions?
No. Each package includes the listed revisions. A revision covers adjustments within the agreed scope, not additional features or unrelated problems.
