Frequently Asked Questions

Can you build a marketplace app like Amazon or Flipkart?
I can build marketplace apps with core features: product catalogs with search/filter, user accounts, cart and wishlist, checkout with multiple payment options, order tracking, ratings/reviews, and seller dashboards. Timeline depends on complexity — a basic marketplace MVP takes 3-4 months.
How do you handle product catalogs with thousands of items?
I use lazy loading, infinite scroll, cached images, and efficient state management (BLoC) to handle large catalogs. The UI renders smoothly even with 50K+ products using virtualized lists and paginated API calls.
Can you integrate with existing e-commerce backends?
Yes. I've integrated Flutter frontends with Shopify, WooCommerce, custom REST/GraphQL backends, and Firebase. I can work with your existing backend or help you choose and set up the right one.
Do you implement push notifications and marketing features?
Yes. I implement Firebase Cloud Messaging for push notifications, in-app messaging, deep linking for marketing campaigns, abandoned cart reminders, and analytics integration (Firebase Analytics, Mixpanel) to track conversion funnels.
