Case Study

Meta excerpt: A cross-platform scratch-card app with a vendor portal that helps brands run gamified promotions while users enjoy instant-win rewards, built with React Native, Django, and cloud-native DevOps for scale.

Executive Summary

Promotions are everywhere, but engagement is scarce. Scratcher fixes that by blending the thrill of instant-win scratch cards with a smooth mobile UX and a powerful vendor portal for brands. Users buy and scratch virtual cards, reveal real rewards, and get notified in real time. Vendors design campaigns, control odds and inventory, and watch sales and engagement dashboards light up. Under the hood, Scratcher runs on a modern stack (React Native + Django + PostgreSQL) and a robust DevOps setup geared for spikes and fast iteration.

The Challenges

• Low engagement in conventional promos: Static coupons and banners rarely spark action.
• Fragmented brand tooling: Marketers juggle forms, spreadsheets, and manual redemptions.
• Peak-time reliability: Flash campaigns cause traffic bursts that break brittle backends.
• Monetization beyond ads: Need for a revenue model aligned with real user actions.

The Solution

Scratcher delivers a playable promotion system:

• A delightful mobile scratch experience with instant feedback and clear redemption flows.
• A vendor portal to create, price, and manage offers with analytics built in.
• Super Admin controls for platform-wide oversight, roles, and audit trails.
• Cloud-native DevOps for auto-scaling, CI/CD, and real-time monitoring.

User Journey

1) Discover & Try

• Open app → explore as guest → browse featured cards → scratch a free sample or low-cost pack.

2) Register & Play

• OTP login → purchase card or bundle → scratch with haptics → reveal reward → guided redemption.

3) Retain & Grow

• Push alerts for new drops, streaks, flash sales → share wins → invite friends for bonus cards.

4) Vendor Journey

• Sign up → create brand profile → design card (art, prizes, odds, supply, validity) → publish → monitor analytics → iterate offers.

Technical Implementation

Frontend

• React Native + Expo SDK for cross-platform app; MST (MobX State Tree) for predictable state.
• Next.js vendor portal with SSR for speed and SEO; Axios/APISauce for typed API calls.
• Three.js for premium effects and interactive motion where needed.

Backend

• Django + DRF for REST APIs and business logic.
• PostgreSQL for transactional data (users, cards, prizes, redemptions, payments).
• Nginx as reverse proxy/load balancer.

Cloud & DevOps

• AWS or GCP hosting with managed DB services.
• CI/CD pipelines for build, test (Jest + Python tests), and deploy.
• Auto-scaling for campaign spikes; centralized logging & metrics for proactive ops.
• Firebase for OTP auth, push notifications, and analytics.

Security Measures

• Tokenized auth, HTTPS everywhere, rate limits on sensitive flows.
• Payment via vetted gateways; PCI-aligned handling on provider side.
• Role-based access, audit trails, and tamper-evident logs.
• Redemption guardrails (one-time codes, expiry, device binding options).

Business Model

• Consumer revenue: Paid card packs, premium editions, bundle discounts.
• Vendor revenue: Subscription tiers or per-campaign fees; optional revenue share on sold cards.
• Add-ons: Featured placement, geo-targeted drops, branded templates.

Success Metrics (What We Track)

• Engagement: DAU/WAU, session length, scratch-to-reward reveal rate, notification open rate.
• Monetization: ARPPU, conversion to paid packs, cost of acquisition vs LTV.
• Vendor impact: Campaign ROAS, redemption rate, time-to-first-value, repeat campaigns.
• Reliability: P95/P99 latency, crash-free sessions, failed purchase rate.
