WHAT I CAN OWN
I can take a product from idea or Figma to production: Flutter architecture and UI, Firebase/Supabase/Node.js backends, REST APIs, authentication, databases, real-time systems, media storage, notifications, payments, maps, analytics, store deployment, maintenance, and scaling.
SOCIAL & COMMUNITY FEATURES
Feeds, profiles, follow/friend systems, likes/comments/shares, short video and media uploads, chat and group messaging, dating and interest-based matching, discovery and recommendations, communities, creator features, moderation, privacy controls, subscriptions, premium access, engagement analytics, and retention improvements.
MARKETPLACE & LOCATION-BASED APPS
I also build multi-role marketplace and location-aware products with listings, search and filters, offers, bookings, orders, Stripe payments, reviews, admin permissions, Google Maps, GPS, background location, geofencing, nearby discovery, route logic, and real-time tracking.
