About this gig

With 5+ years of hands-on Flutter development, I've shipped production apps used by real users at scale including a FinTech app with 500K+ downloads and an on-demand marketplace app with 100K+ downloads. Whatever kind of app you're building, I can take it from idea to app store.

What I bring to your project:

  • End-to-end Flutter development for iOS & Android from a single codebase
  • Experience across e-commerce, fintech, HR/enterprise, on-demand/marketplace, e-learning, and AI-powered apps
  • Secure authentication (Firebase Auth, OAuth2/Keycloak)
  • Firebase integration: push notifications, Firestore, Cloud Functions, Crashlytics
  • Clean, maintainable architecture (BLoC/Provider/GetX your choice)
  • REST API & third-party integrations
  • App Store & Play Store submission support

Some of what I've delivered:

  • A FinTech remittance app 500K+ downloads
  • An on-demand services marketplace 100K+ downloads
  • A job-matching platform 10K+ downloads
  • An AI-powered attendance system with background location/WiFi tracking
  • AI chatbot features with interactive UI, not just plain text replies

I treat every project like it's going into production: clean code, honest timelines, clear communication.
