🛒 Enterprise Smart POS Dashboard (AI-Ready)

An enterprise-grade, state-driven Point of Sale (POS) frontend application. Engineered with modern stateless security architectures, concurrent transaction handling, and integrated predictive analytics engines.

🚀 Architectural Breakthroughs (What I Built)

• Stateless Security Gateway: Integrated secure JWT login flow with automated token injection via HTTP Authorization headers for protected backend transactions.
• Session Persistence: Implemented proactive session monitoring leveraging browser storage layers to handle automatic termination on credential expiry.
• Concurrent Checkout Processing: Developed high-throughput cart processing utilizing asynchronous JavaScript synchronization primitives (Promise.all) to process checkout loads concurrently.
• Predictive AI Analytics Blueprint: Embedded a contextual interface using the @google/generative-ai SDK, mapping live PostgreSQL database state arrays into large language model context windows for business reporting.
