​Authentication Systems: Email/Password, OTP, Google, Apple, and OAuth login flows.

​Cloud Storage Configuration: Cloudflare R2 and Cloudinary integration for secure file, video, and image storage.

​REST & GraphQL API Integration: Clean Dart code utilizing http or dio packages with state management.

​Real-Time Features: WebSockets, live chat messaging, and push notifications.

​Automated Engines: Server-side/client-side PDF document generation engines (Invoices, Reports, Certificates).


​WHY WORK WITH ME?

​Production-grade security (RLS policies & clean environment variables).

​Clean, well-structured Dart data models (freezed, json_serializable).

​Fast response times and clear updates throughout the build.
