About this gig

FlutterFlow Mobile App Developer | Firebase, Custom Widgets & API


A great app starts with more than a good looking interface, it needs the right logic, backend, and functionality underneath.

I'm a FlutterFlow developer helping startups, entrepreneurs, and businesses build functional, scalable mobile apps that are ready for real users.

Whether you need an app built from scratch, an existing FlutterFlow project upgraded, or complex functionality added, I can handle the development from UI to backend.


My services include:

  • Full FlutterFlow iOS & Android app development
  • Firebase Authentication, Firestore & Storage
  • REST API & third-party integrations
  • Custom Widgets & Custom Functions
  • Payment gateway integration
  • Push notifications & advanced workflows
  • AI features and automation
  • Admin dashboards & user management
  • Bug fixing and performance optimization

I’m Nicky I design and develop mobile apps and websites with a focus on what happens beyond the screen. I care about how easily it can adapt as your business changes. From mobile applications and customer portals to business websites and web platforms. I can handle the interface, functionality, integrations, backend connections, and responsive experience needed to make a product feel complete. If you have a rough idea, an existing website or app that needs rebuilding, or a project that has become difficult to finish, send me a message now and let figure it out.
