Role: Frontend Developer – Flutter (Mobile) & React (Web, Shared) Team: 2 Developers – I handled Flutter mobile and admin web UI (React); my partner handled backend Tech Stack: Mobile (Flutter), Web Admin (React.js), Backend (Laravel), WhatsApp OTP API, Firebase

Local F&B businesses often use outdated loyalty systems that are hard to track and manage. The client needed a custom, digitally powered loyalty platform to replace stamp cards and offer real-time rewards with customer insights.

Coffee Farm is a custom loyalty app built for a café. It allows customers to earn points for their purchases and redeem them for menu items. The solution includes:

A mobile app for customers

A React-based web dashboard for staff/admins

📱 Mobile App (Flutter – Built by Me)

WhatsApp OTP login flow

Display point balance

Generate QR code for in-store scanning

View available rewards and redemption options

🖥️ Admin Web App (React – Built by Both)

Customer management and lookup

Scan customer QR codes to award points

View customer point transaction history

Manage redeemable rewards (create/update)

Configure point conversion rates (e.g., 1 point per IDR X)

⚙️ Backend (Handled by My Partner)

WhatsApp OTP verification & user auth

Point accumulation & redemption logic

Admin-user role management

QR code and transaction processing

I led the project from concept to launch:

Designed and built the Flutter mobile app for customers

Built the React.js admin dashboard with full CRUD capabilities

Developed secure backend with Laravel, handling auth, user data, point logic, QR code generation, and reward tracking

Integrated WhatsApp OTP flow for smooth login experience

Deployed and maintained both apps in production environments

I’m currently available for freelance work — whether you're looking for a full-stack development team to scale a product, or need someone to turn an MVP idea into a functional app (from design to live deployment).

I work fast, stay lean, and focus on delivering clean, maintainable solutions that actually ship.

Let’s build something great — whether it's a bold idea, a side hustle, or the next big platform.
