Secure Lead Retrieval System: Empowering Events with Cybersecurity and DevOps

Secure Lead Retrieval System: Empowering Events with Cybersecurity and DevOps

Project Summary

The Secure Lead Retrieval System is a web and mobile application designed to streamline event interactions, inspired by advanced lead retrieval platforms. Attendees use personal devices to scan product stickers, access exhibitor information, build personalized product lists, and add notes. Exhibitors manage sticker orders, product data, and sticker sets through a secure web portal, while onsite staff handle sticker management and printing. The system supports offline lead capture with seamless synchronization to a central show database upon reconnection. Built with DevOps-driven CI/CD pipelines and cybersecurity best practices, it ensures scalability, reliability, and protection for high-performance event operations.

Key Challenges Addressed

  • Manual Process Inefficiencies: Legacy lead retrieval methods were time-consuming and error-prone.
    Solution: Automated lead capture and sticker management with a Flutter-based mobile app and Spring Boot REST APIs.
  • Data Security Risks: Unsecured data transmission posed risks to sensitive attendee and exhibitor information.
    Solution: Implemented JWT-based authentication, RBAC, and TLS encryption to secure data pipelines.
  • Offline Connectivity: Events often occur in low-connectivity environments, disrupting real-time data access.
    Solution: Integrated Firebase for offline lead capture and synchronization, ensuring uninterrupted operations.
  • Scalability Needs: High-volume events required robust, scalable infrastructure.
    Solution: Leveraged Docker, Jenkins, and Kafka for scalable, automated deployments and real-time data streaming.
  • System Reliability: Ensuring consistent performance under varying loads and potential cyber threats.
    Solution: Conducted rigorous QA testing and penetration testing with OWASP ZAP to maintain system integrity.
