Cross-Platform Rewards Redeem System

I need a redeem (rewardd) system similar as LMCTplus.com so will all same features on both web and mobile.

Check lmctplus before you bid please

Please plan for these concrete deliverables:
• Responsive web app with full voucher redemption flow
• Companion iOS and Android builds from the same code base
• Admin dashboard to upload new voucher batches, set point costs, and review redemption logs
• REST or GraphQL API documentation

Acceptance criteria will be a live staging site and testflight / apk builds where I can create a user, earn points through mocked purchase, referral, and engagement events, and successfully redeem and view a voucher.
