Retail Inventory Management System Cloud/Serverless Project

Project Overview

We designed and implemented a Retail Inventory Management System tailored for modern retail operations. This system leverages cloud-native architecture, real-time data synchronization, and secure access control, enabling businesses to manage inventory more efficiently while reducing operational overhead.

Technologies & Skills Used

• Cloud & Serverless Architecture: Firebase Cloud Functions, Google Firestore, Python, Firebase Admin SDK
• Development Best Practices: Git, Python envs, Firestore emulators, config/logging
• Security & Access Control: Firestore Security Rules, Admin SDK, secure ops
• Data Architecture: Optimized Firestore structure, custom indexes, real-time sync

Key Features

• Purchase Order Management with real-time status tracking
• Efficient querying and business workflow indexing
• Event-driven, auto-scaling, microservices-style architecture
• Full local emulation, debug logging, and environment separation

Code Showcase

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Invoice App',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

void _submitData() {
  FirebaseFirestore.instance.collection('invoices').add({
    'invoiceId': invoiceId,
    'products': products,
  }).then((value) {
    setState(() {
      invoiceId = '';
      products.clear();
    });
    ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Invoice submitted!')));
  }).catchError((error) {
    ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text('Error: $error')));
  });
}
