Product Verification App
Tech Stack
Project Description
A secure product verification system using QR serial numbers with polynomial equation method and RSA encryption, processing 100+ verifications daily.
Developed for HANUVEEN Pvt Ltd, this product verification app provides a robust solution for authenticating products and preventing counterfeiting.
The system employs a sophisticated approach using QR codes with embedded serial numbers, secured through a polynomial equation method and RSA encryption. This ensures that each product has a unique, tamper-proof identifier that can be easily verified by consumers.
The backend infrastructure is built on Node.js with a Flutter mobile application for end-users. Data is stored across PostgreSQL, Redis, and DynamoDB to optimize for different access patterns and performance requirements.
Deployed on AWS using EKS, ECS, Lambda, RDS, and DynamoDB, the system achieved a 30% improvement in reliability. The solution currently handles 100+ active users and processes 10,000 product verifications daily in the internal CRM.
