Experience
eCommerce Portal
Key features include JWT-based authentication, role-based access, product search by category, a secure payment gateway, email and WhatsApp notifications, and sales/analytics reports.
Challenges faced included performance optimization, database scalability, authentication and authorization, and state management across multiple components. To resolve performance issues, we implemented lazy loading, AOT compilation, and server-side pagination. We optimized database queries for faster results and handled unauthorized access and data breaches through JWT-based authentication, password hashing, and role-based access control. State management was addressed using NgRx (Redux) to handle complex states across components.
Para Solution Website and Employee Portal
Key challenges included performance optimization, real-time attendance tracking, delays in leave approval, and payroll processing. To address performance issues, we implemented lazy loading, caching, and query optimization. For real-time attendance, we integrated RFID and biometric systems and used geolocation tracking for field employees. We also automated the leave approval and payroll processing workflows.
