Внедрение Firebase Authentication + Функционал для платных услуг

Budget: 500 USD Deadline: 7 days

Hello,

I have reviewed the task. I can help with the implementation of Firebase Authentication and the realization of paid services functionality on the existing website.

I have experience working with authorization systems and API integrations. I propose to implement the project in stages:

— Setting up Firebase Authentication (email / phone / login flow)
— Integration of user registration and login
— Implementation of basic paid access logic (user rights, statuses)
— Connection with the backend (via API, if available)

💰 Cost: 400 – 500 USD (depends on details and payment)
⏳ Deadline: 5 – 7 days

If payment system integration (Stripe, etc.) is required — we will discuss separately.

I am ready to clarify details and start working. Expand

Hello, I worked on a Dating App with Firebase Auth and a payment system - I added social media authentication, premium subscriptions, and processed over 15,000 users monthly.

Are you planning to integrate different payment methods for premium features, or will there be one main provider for processing payments?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

I worked on https://poseidon.codezerogroup.com — a platform with a complete user authentication system, subscriptions, and payment integration; exactly the same scope as here.

My contacts in Canada have a functioning service, so it is crucial to implement it without risk — Firebase Auth with social login and email/password, then Stripe or PayPal with webhooks to manage subscription status. I secure routing on the front end and Firestore rules on the back end, so users without an active subscription do not have access to paid features.

What I will do:

- Implement Firebase Authentication (email/password + social login)
- Payment integration (Stripe or PayPal) + handling of recurring subscriptions
- Secure routing — blocking premium features for non-logged-in / unauthorized users
- Handling payment webhooks + automatic account status update
- End-to-end testing + integration documentation

--- OPTIONS ---

- Option A (Auth + payments): 500 USD (7 days) — Firebase Auth + payments + route security
- Option B (Auth + payments + panel): 800 USD (7 days) — like A + admin panel: user statuses, payment history, subscription management — best scope/price ratio
- Option C (Premium): 1040 USD (7 days) — like B + email notifications, reporting, full onboarding flow

Completion time: 7 days. I need access to the repository, the Firebase project account, and payment provider data.

Portfolio:

- https://poseidon.codezerogroup.com — enterprise platform with user authentication and payment integration
- https://ou-uv.com — multilingual application with API, session management, and access control
- https://codezerogroup.com — B2B platform with an access system and client panel

5 years in web development — from simple landing pages to complex platforms with auth, payments, and admin panels.

Write to me — I will start after receiving access.
