Integrate Google Classroom API into the system with a mobile application (Flutter).

Budget: 18000 UAH Deadline: 14 days

Good day!

I have reviewed your project for integrating the Google Classroom API into the system (Flutter mobile app + Laravel backend + web version) — the task is clear, focusing on authorization, data synchronization (courses, assignments, users), and stability. I have experience with Google APIs (OAuth, Classroom SDK), Laravel Socialite for authorization, and Flutter (google_sign_in package). I am ready to implement full integration with minimal changes to the existing code.

Proposal: We will use Laravel Socialite for Google OAuth on the backend (storing tokens in the database), google_sign_in + googleapis_auth for Flutter. Synchronization through Laravel API endpoints, with caching (Redis) for stability. I will prepare a guide with steps (Google Cloud setup, tokens, updates).

Work plan (1–2 weeks, with a demo every week):

Google Cloud setup (1–2 days): Creating a project in the Console, activating the Classroom API, OAuth clients (for web/Flutter), testing access.
Authorization (3–4 days): Integrating Google Sign-In into Flutter (mobile) and Laravel (web), storing/updating tokens (refresh tokens) in the database.
Data synchronization (4–5 days): API endpoints for retrieving courses/assignments/users (Classroom API v1), displaying in the app/web, bidirectional synchronization with conflict checking.
Testing + documentation (1–2 days): Load testing (tokens, API requests), documentation (steps, code snippets), deployment.
Clarifying questions:

What version of Laravel/Flutter? Is there ready access to Google Cloud (project ID)?
Data volume (number of courses/users at the start)? Is full synchronization needed or just reading?
Are there specific screens in Flutter for displaying (courses, assignments)?
Database: MySQL/PostgreSQL? Is migration needed for tokens?
Budget: fixed or hourly (150 UAH/hour)?

Hello.

I have quite a few questions, here are some of them:
1. As I understand, your system already has login and password authorization. Should the Google authorization be implemented as a completely alternative method of authorization, or should the user have the option to link their Google account to their existing account created with a login and password?
2. Is there a need for account merging logic? For example, if there is already an account in the system with email X, what happens when authorizing through Google with the same email?
3. Is it only necessary to read data from Classroom, or do we also need to create courses/tasks from our application?
4. "The ability to receive and display courses, tasks, and users in the application." Am I correct in understanding that the task does not include the implementation of full user interfaces for displaying courses, tasks, and users?
5. Does the task include writing a complete detailed technical specification and designing the solution at least at the business level? Or is this already implemented/will be implemented on your side?

In any case, please write, I would be happy to discuss the details. Currently, my rough budget estimate is $2000-$4000.
