Full-Stack Developer Needed for QR Reward Tracking MVP [Urgent]

We are building an MVP system for LuckySip, an offline-to-online customer engagement platform for cafés. The system must track QR scans per café, collect name, email and card number from customers, and use the café ID, card number and date to pick the right reward message, email template, and affiliate campaign link. Once a customer submits their info, your backend needs to send an automated reward email. The CTA button in this email must go through a LuckySip tracking redirect to record the click before landing on the correct Awin affiliate link with the appropriate parameters. The MVP requires a shared reward page, QR source tracking, backend database and logic, CSV import features for cards and campaign links, automated transactional emails set up with SPF/DKIM/DMARC, tracking redirects before affiliate links, click logging, a basic admin dashboard, and CSV export for reports. We do not need mobile apps, customer accounts, a café dashboard, or complex gamification. We’re looking for a full-stack developer with experience in backend systems, database design, CSV imports, automated emails, tracking redirects, and admin dashboards.

Budget range:
Large project ($3,000 – 5,000 USD)
