NIZAAM is a retail management SaaS designed for mobile shops and small retail businesses to manage their daily operations from a single system. The platform helps shop owners handle sales, inventory, suppliers, expenses, accounts, and business reporting without relying on multiple separate tools. I developed NIZAAM using Flutter and Supabase, with a strong focus on real-world retail workflows, data accuracy, and ease of use. The system includes product and stock management, sales recording, supplier management, account transactions, expense tracking, reporting, authentication, and role-based data access. The backend is built on Supabase PostgreSQL with Row Level Security (RLS) to keep business data isolated and secure. The architecture is designed to support multiple users and branches while keeping the app simple enough for everyday shop operations. I also worked on the database structure, business logic, authentication flows, reporting modules, and synchronization between the Flutter frontend and backend. Key Features:

Sales and transaction management

Product and inventory tracking

Supplier management

Expense and account records

Business reports and analytics

User authentication and access control

Multi-user / branch-ready architecture

Secure Supabase backend with PostgreSQL & RLS
