Academic Study Web & Android App

I want to launch an app that lets students keep their academic life organised from any device. The core idea is simple: a single platform—both browser-based and as a dedicated Android build—where users can view materials, follow a structured study plan and track their academic progress.

Scope
• Two front-end targets: responsive web portal and native Android app, sharing one back-end.
• Smooth login/registration, preferably through e-mail and Google.
• A clean dashboard where students can browse courses, open lessons and monitor their progress.
• Admin side for uploading or editing course content, scheduling assessments and managing users.

Tech preferences
I am open to modern stacks; React or Vue for the web front end and Kotlin or Flutter for Android would be great, but I’m flexible if you have a better approach. A REST or GraphQL API plus a secure database layer (PostgreSQL, Firebase, etc.) is expected.

Deliverables
1. Source code for web app, Android app and back-end.
2. Deployment guide and basic documentation.
3. Short hand-off call or recorded walk-through once the build is complete.

If you have built study or learning platforms before, I’d love to see them. Let me know roughly how long you’ll need and any questions you have so we can get started.
